The factory replacement Felt Pro head gaskets work good. P/N 9441-pt. Do not ever, EVER use ROL brand head gaskets, though. They look exactly like the stock and Felpros but they lack a wire fire ring inside the gasket and they'll blow at near nothing boost wise. Cosmetics are my favorite gaskets these days but they require machining both the block and head decks to a smoother finish to work properly. Stock surface prep? Stick with the Felpros.
