[DeTomaso] Inlet Manifold gaskets

[jderyke at aol.com]

I agree with Rich. I prefer Fel-Pro on my 351-C street builds and have had NO leakage of either air/fuel or oil, ever, if things are used per directions. I note that Ford Motor Co. recommends some Fel-Pro gaskets in their current catalogue which has pitifully few Cleveland parts nowadays. Not the first screw-up from Roush Motors I've heard of, since our friend John Christian left them. 
FWIW- J DeRyke

I have had good luck with the Felpro performance series of gaskets on
   my Windsor motors.
    Failure is usually improper installation.
   In this case it appears they used the wrong type of silicone,and way
   too much of it.Black is for oil,not water.Blue is for gaskets around
   water.
   I use a very small amount of the ultra blue around the water ports.Use
   ULTRA blue as it is sensor safe,versus normal blue which is not.I seem
   to recall you have fuel injection,hence sensor safe is needed.Wear
   latex gloves,and use a finger to spread it around the port on both
   sides of the gasket.Let it set for at least 15 minutes to skim over.Any
   excess will get pushed out either into the lifter valley or into the
   cooling system,so only use a small amount of the silicone.You use the
   silicone to help keep the gasket in place and to make up for very minor
   gaps or porous surfaces.If it has a large gap.Get the heads/intake
   machined or replace them.
   I also do not use the cork or rubber end seals.I use ultra black or
   ultra grey instead.This area does get a large bead of the silicone as
   it has to replace the cork/rubber end seals which are around 3/8 of an
   inch thick.This area has to be really clean before you can use
   silicone.Any oil on the surface and it will not stick and it will leak.
   Good luck, Richard
