[DeTomaso] 4V cc iron heads

[Charles Engles]

Dear Metallurgists,


      FWIW. Current data from this morning from the machine
shop--------------------------

                4V quench heads                   $400


                Trick 5/16" valve guides          $125
                Labor valve guides                $96
                Trick valve job                   $250
               Trick hollow 5/16" intake valves   $483
               Trick hollow 5/16" exhaust valves  $231

                Current *intermediate* total     $1,585


          Still pending:  Trick beehive valve springs and retainers plus
labor
                          Machine shop work to properly affix Funnel web
port stuffers
                          Flow testing

                              Figure another $500 easy


             Rough approximate cost for a pair of iron quench heads with FW
port stuffers (flow bench:  318 cfm at .60" lift....) to match Parker Funnel
Web 4V Intake manifold:  $2,100+ ready to bolt on.


            The project continues at the Pantera Research Institute.

It's not a little more--it's a LOT more.   But I doubt you can do what you 
want to do to your iron heads for only $500.   I suspect it would be much 
more than that--assuming your machining them for roller rockers, etc.

You're looking at $2000 for a complete set of Edelbrock aluminum heads.   
$1400 bare.   Those are good street heads, but if you are building a
stroker, 
they would need some expensive work.   Better to step up to CHI heads, 
which are $1895 bare, or $2500 (ish) complete.

Have you actually done the math to determine what you would have invested 
in your iron heads by the time they were ready to bolt onto the motor?

Mike
