I recently rebuilt my 302. I used felpro gaskets. I can�t stopmy valve cover gasket leaking. What is the best brand gasket to use?
BEST Gasket makes a valve cover gasket that is thicker than others and has worked well for me. It is new cork & you can feel the difference. They also make the only rear main seal I'll ever use. Right Stuff works well & seals completely but is tough to get it off again. There is probably a way to deal with that if you let it cure before assembly.
Make sure the cover is good and straight as well. You could always just run a Good bead of Black RTV around the cover Let it cure out 100% before installing it.
