replacing the gaskets in my race engine right now and realized i have always used stock replacement felpro gaskets. not their high performance ones... just stockers. i should prolly try something a little more robust. what part numbers are you guys using? iron block and heads. stock bore 5.0
I have used Fel Pro on my carbed 5.0's since the 80's with no issues. Both the 9333 that someone mentioned and the 1100 number, which, iirc, is the performance gasket. Have the 1100 type on the 82's engine and have numerous passes and sprayed passes with iron Gt40 heads, no issues.
