Valve Stem Seals-gctid367728

[Guest Close Guest]

I am almost afraid to ask this, but... What kind of Valve Stem Seals and brand would you guy's suggest for a 1988 through say 1992 5.7, 350?

There is no grove in the stem other than for the locks.. The valves are Stainless Steel if that makes a difference..

Thanks Guy's, Jim

Jim, this is one where I'd feel safe letting your machine shop guy help make a decision.

There are several types; Umbrella style, O-ring style, Posi-Loc, etc, and he may have a recommendation for one that he prefers. More than likely these will be included in the gasket kit that he selects.

GM high performance seals.



Summit sells a similar version.



http://"http://www.enginebuildermag.... Larry Carley.

I've linked to Larry's articles re; pistons, quench, etc, several times over the years.

Jeff Smith or Dennis Moore would be another good source for info.

If you increase valve lift substantially, be sure to check for valve spring keeper/seal interference.... such as with the Vortec cylinder heads.

Jim, as to your opening comment "I am almost afraid to ask this, but"............, understood.

I did load you up with quite a bit of information http://"http://www.baylinerownersclu...r other thread regarding the SBC quench effect.

I was rather lengthy, but as you can see, I'm pationate about this type of build for our Marine applications...... and in particular for our heavier hulls.

I hope that it made some good sense.

Whether you choose that style build or not, I do wish you the best of luck.
