    Rated 1 out of 5 by from not happy I purchased these replacement head gasket for my gm performance engine thinking they were some kind of special gasket for the price. When I got them shipped I opened them and they are just felpro gaskets in gm performance wrapping....and 30.00 a piece more than felpro.
