What are you big dawgs running for head gaskets in you turbo SBC and BBC ? and at what boost ? I picked up a set of FelPro Performance MLS head gaskets (#1142) . It seems these and the Cometic's are the the ones to use . I "heard" these Felpros are are just like cometic , but "supposedly" better. a few $$ cheaper and less weeping problems .
