There are some safety issues (I assume not commonly encountered or GM would not use them):

I'm fascinated by sodium cooled valves, but I think titanium is a more popular option in this crowd.  There were some made available for racing and while they do not have a cooling technology they do endure more heat than a stainless valve.  They come up on ebay or a swap meet occasionally.
I just have a street engine so I'm not concerned... just fascinated.

LSJ[[1]edit]

   Ecotec LSJ engine in a 2006 [2]Saturn Ion Red Line
   The LSJ is a supercharged version of the LK9 Ecotec 2.0 La 1,998 cc
   (121.9 cu in)a with an [3]Eaton M62 [4]Roots-type supercharger and
   air-to-liquid [5]intercooler. The LSJ shares many of its components
   with the LK9 such as: piston cooling jets, oil cooler, pistons,
   connecting rods, crankshaft, oil pan, sodium-filled exhaust valves and
   cylinder head.^[6][8] It is rated at 205 hp

2.0 LNF[[7]edit]

   Ecotec LNF in a [8]Pontiac Solstice
   A turbocharged [9]direct injected (redubbed Spark Ignition Direct
   Injection) Ecotec was introduced in the 2007 [10]Pontiac Solstice GXP
   and [11]Saturn Sky Red Line. In these applications, the engine is
   mounted longitudinally. Displacement is 2.0 La1,998 cc (121.9 cu
   in)awith a square 86 millimetres (3.4 in) bore and stroke. Compression
   is 9.2:1 and maximum boost is 1.4 bar (20.0 psi), delivering 260 hp
   (190 kW) at 5300 rpm and 260 lbA.ft (350 NA.m) of torque from 2500 to
   5250 rpm. Engine redline is at 6300 rpm and premium fuel is
   recommended. The sodium filled exhaust valves were based on technology
   developed for the Corvette V8 powertrains. The sodium fuses and becomes
   a liquid at idle, which improves conductivity and draws heat away from
   the valve face and valve guide towards the stem to be cooled by the
   engine oil circulating in this area.[12]sodium-filled stainless steel

   A 2.0 L (1998 cc) [45]turbocharged direct injection version of the gen
   III Ecotec will be available in 2013 [46]Cadillac ATS and [47]Chevrolet
   Malibu.This engine is also available in [48]Cadillac XTS in Chinese
   market. Bore and stroke are both 86.0 millimetres (3.39 in),
   compression is 9.5:1. The engine uses [49]twin-scroll turbocharger with
   electronically controlled wastegate/bypass valve, air-to-air
   intercooler, stainless steel dual-scroll (1a4, 2a3) exhaust manifold
   designed to withstand 980 ADEGC (1,800 ADEGF) turbine temperature, and
   [50]rotacast aluminum alloy (A356T6) cylinder head with sodium-filled
   exhaust valves

   ford FE "The intake and exhaust valves are larger than those found on
   the 427 production engine". The exhaust valves feature a sodium filled
   hollow stem for better heat conduction

   5.0-liter V-8: 435 hp, 400 lb-ft
   Fordas Coyote V-8 carries over as well, although it receives more
   substantial changes. Mustang engineers used the [51]low-volume Boss
   302as V-8, a [52]glorious-sounding 444-hp powerhouse, as its
   performance bogey. Unfortunately, the Boss engine incorporated some
   expensive manufacturing tricks that Ford couldnat possibly use in a
   mass-produced engine, like hollow intake valves, sodium-filled exhaust
   valves, and CNC-ported heads, so it had to look elsewhere to approach
   Boss power levels.


   The 1963 Indy pushrod engine produced 375 BHP at 7200 RPM from 255
   cubic inches
   Ford powered Lotus cars were prepared for Indy in 1963, to be driven by
   Dan Gurney and Jimmy Clark. The high performance 260 used in the Cobra
   was the starting point, dubbed the Stage 0 engine. Stage 1 involved
   revised and enlarged intake and exhaust ports, and 12.5:1 compression
   through the used of forged pop-up pistons. The special intake manifold
   carried four 46mm downdraft Webers carburetors. Larger valves,
   hollow-stemmed intakes and sodium-filled exhausts were fitted to the
   heads, along with high silicon content aluminum alloy retainers.

   Subject: Re: [DeTomaso] Sodium valves
   sodium filled exhaust valves were also used on the corvair turbo
   charged engines  from 62 on to the end of the 68
   all 911 engines up to the 964  have sodium filled exhaust valves .
   lt-4 zo6 had sodium filled exhaust valves . all turbo and supercharged
   chevrolet engines have had sodium filled exhaust valves from the
   factory. ls7 included
   On the exhaust side, sodium-filling is the best way to increase the
   head cooling capacity of a hollow exhaust valve. If stock diameter
   steel valves are required, but a valve weight is not mandated, going to
   a hollow intake and sodium-filled exhaust is certainly a major
   advantage. better cooling of the valve and the guide as well as lighter
   than other types except titanium .
   Stainless steel (for street performance) has much better durability
   characteristics than titanium, and the street guys wonat usually see
   the real benefits of titanium. In racing, use titanium when you want to
   lose weighta|and spend a lot of money. sodium filled exhaust valves
   were an off shoot spin off from the aircraft engines way back .

     Yes, that sounds reasonable. I think it was for use in aircraft
   engines
     with some form of supercharging that they were originally developed.
   I
     just didn't realize they were back in style!

     What I read said the stock LS7 has sodium filled exhaust valves.
     I would guess that a turbo charged production engine might have them
   to
     handle the heat?

         Thanks Charles
       I wouldn't be surprised if sodium valves were used in Nascar hemis
   or
       Boss 429 engines too. I just don't recall any production engines
   with
       them, but I could be wrong.....
       Ken Green says the LS7 uses them !
       I'm surprised at that. I wonder if that's in the GM engine as
     produced
       or an aftermarket thing?
       Ken, do you know?

       Hi Barry your info was almost rite on.  Ford did offer the sodium
       valves on the 427 engines for thr Cobras used in their race program
       There was a issue with the nos valves as the sodium corroded the
     inside
       causing them to come apart as they were drilled to make the stem
       hollow..the story I heard was the sodium was to provide cooling of
     the
       valve stem in endurance racing...we used some
       In drag race engines as they were somewhat lighter..a much better
   set
       up would be manley stainless valves..?..Pete Coleman
       At manley in Lakewood n.j. 732-905-3366 would be able to help you
   on
       this issue.

         Hi Robert
         Sodium valves were a feature in the 375HP version of Corvette 327
         engines
         with fuel injection. I don't recall sodium valves being used in
         other US
         standard production engines. Maybe some other exotic engines did.
         Later
         valve steels and technology made the risks and expense of sodium
         filled
         valves obsolete in HP engines. The idea originated in aircraft
         piston
         engines back around WWII, I think, and was related to trying to
     cool
         exhaust
         valves under high stress loads.
         The 1971 Cleveland 351-4V engines in Panteras (and Mustangs,etc.)
         had high
         compression closed chamber (quench) heads, single point
         distributors, small
         square bore 600cfm 4300A carbs and 2 bolt mains. The Boss 351 was
         the only
         351C to get 4 bolt mains, dual point distributor and the large
         spreadbore
         Motorcraft 4300D carb in 1971 along with high compression CC
   heads.
         Some people have said that some 1971 4V engines found there way
     into
         very
         early 72 Panteras, but probably only in early January 72 cars.
   The
         1972
         Cobra-jet engines would have entered production in Sept of 1971
   and
         by the
         end of 1971, DeTomaso was likely to have used their engine stock
   on
         hand and
         have received new Cobra-jet engines from Ford. I understand
     DeTomaso
         was
         generally receiving engines only about a month or so after they
     were
         produced in the US plant.
         1972 Panteras came with Cobra-jet engines that had open chamber
         (lower
         compression) 4V heads but with 4 bolt mains, dual point
   distributor
         and
         large spreadbore Motorcraft 4300D carb. This was the strange
   result
         of Ford
         trying to recover some of the power lost to stricter emission
         standards for
         1972. The compression had to come down for unleaded gas and Ford
         upped the
         RPM to try to get some oomph back. They retarded the cam timing
   and
         hopped
         it up a bit to get the power at higher revs, thus the dual point
     and
         4 bolt
         mains.
         1973 and 74 went downhill from there, with increasing emissions
   and
         lower
         compression.
         So...the best heads were in 1971, but everything else was better
   in
         1972.
         Unless you have a 1971 BOSS 351 engine, which never came in a
         production US
         market Pantera. Pity that.

   I'm fascinated by sodium cooled valves, but I think titanium is a more
   popular option in this crowd.  There were some made available for
   racing and while they do not have a cooling technology they do endure
   more heat than a stainless valve.  They come up on ebay or a swap meet
   occasionally.
   I just have a street engine so I'm not concerned... just fascinated.

     GXP
        and [11]Saturn Sky Red Line. In these applications, the engine is
        mounted longitudinally. Displacement is 2.0 La1,998 cc (121.9 cu

     Compression
        is 9.2:1 and maximum boost is 1.4 bar (20.0 psi), delivering 260

        recommended. The sodium filled exhaust valves were based on
     technology

     becomes
        a liquid at idle, which improves conductivity and draws heat away

     diameter
        steel valves are required, but a valve weight is not mandated,
     going to
        a hollow intake and sodium-filled exhaust is certainly a major
        advantage. better cooling of the valve and the guide as well as
     lighter

        Stainless steel (for street performance) has much better
     durability
        characteristics than titanium, and the street guys wonat usually
     see
        the real benefits of titanium. In racing, use titanium when you

          with some form of supercharging that they were originally

              Hi Robert
              Sodium valves were a feature in the 375HP version of
     Corvette 327
              engines
              with fuel injection. I don't recall sodium valves being
     used in
              other US
              standard production engines. Maybe some other exotic
     engines did.
              Later
              valve steels and technology made the risks and expense of
     sodium
              filled
              valves obsolete in HP engines. The idea originated in
     aircraft
              piston
              engines back around WWII, I think, and was related to
     trying to
          cool
              exhaust
              valves under high stress loads.
              The 1971 Cleveland 351-4V engines in Panteras (and
     Mustangs,etc.)
              had high
              compression closed chamber (quench) heads, single point
              distributors, small
              square bore 600cfm 4300A carbs and 2 bolt mains. The Boss
     351 was
              the only
              351C to get 4 bolt mains, dual point distributor and the
     large
              spreadbore
              Motorcraft 4300D carb in 1971 along with high compression
     CC
        heads.
              Some people have said that some 1971 4V engines found there
     way
          into
              very
              early 72 Panteras, but probably only in early January 72
     cars.
        The
              1972
              Cobra-jet engines would have entered production in Sept of
     1971
        and
              by the
              end of 1971, DeTomaso was likely to have used their engine
     stock
        on
              hand and
              have received new Cobra-jet engines from Ford. I understand
          DeTomaso
              was
              generally receiving engines only about a month or so after
     they
          were
              produced in the US plant.
              1972 Panteras came with Cobra-jet engines that had open
     chamber
              (lower
              compression) 4V heads but with 4 bolt mains, dual point
        distributor
              and
              large spreadbore Motorcraft 4300D carb. This was the
     strange
        result
              of Ford
              trying to recover some of the power lost to stricter
     emission
              standards for
              1972. The compression had to come down for unleaded gas and
     Ford
              upped the
              RPM to try to get some oomph back. They retarded the cam
     timing
        and
              hopped
              it up a bit to get the power at higher revs, thus the dual
     point
          and
              4 bolt
              mains.
              1973 and 74 went downhill from there, with increasing
     emissions
        and
              lower
              compression.
              So...the best heads were in 1971, but everything else was
     better
        in
              1972.
              Unless you have a 1971 BOSS 351 engine, which never came in
     a
              production US
              market Pantera. Pity that.
