I've had good luck with the Cometic gaskests that come with the Wiseco pistons.

Dont need a larger gasket kit till you run a 440 so a stock size will do fine.

You want cometic brand multi layered steel (MLS) gaskets. Can get them on ebay. The picture and what you get should be a rubber coated metal gasket. Not fiber.
