Agree with HBJET, Cometic is offering a superior product at this time.

I have never run a Cometic gasket.I have used the Felpro 1017-1 for years with no problems.Unless you are running very high compression or alot of boost the Felpros are the way to go.
But I dont think they make the cross over head gaskets though.
Where I think cometic will make pretty much any gasket you send them a pattern for.
With out spending a million bucks i guess the fel pro 1017-1 is what i needed.I have merlin heads and that is the gasket that they want on the motor....input very much appreciated :220v:
