What do you guys use that does not leak? I have cork or the felpro rubber gasket. Not the center bolt valve covers. Just some GM performance covers.

Just put a thin coat of silicone.

i always used cork......just a little silicone to the valve cover and stick the gasket to it....dont use any silicone to stick the gasket to the head......then you can use the gasket several times before it leaks....you know like when you need to adjust your roller rockers.:yes:

I use the extra-thick cork and RTV them to the valve covers. The benefit of using the extra thick style is that the flanges of the valve covers won't touch on an aftermarket intake manifold impeding the seal. I can use the same set for years even with frequent removal to check valve lash.

I agree, but the steel core rubber gaskets work really well too. I think that the best recomendation is to make sure to use silicone on the valve covers to install the gaskets to them.

I use the Moroso blue ones with the steel in the rubber!!!

felpro 1604 cork rubber with steel core.....works nicely

I have had good luck by glueing the CORK gaskets to the Valve cover. No glue between the gasket and the Head.
