which valve cover gasket to use?

[Nick Micale]

Those bottom ones are felpro perma dry plus. ....They are not cheap and they are the best out there BAR NONE!.......

My experience with these gaskets have been ok with street cars, but NOT so much on performance builds.

At higher boost, mid-20's, they will blown out and leak like crazy.

I have to go with Bison on this one, cork gaskets have served us the best.

You can re-use them many times if you stick them to the valve cover properly.
