Description
Set of 2 copper cylinder head gaskets for 18-20hp 35 cubic inch small block Briggs Vanguard engine. Gaskets are .031 thick. Copper gaskets can be used when putting orings in the cylinder heads for better sealing and are reusable. We recommend a thin coat of copper silicone on both sides of the gasket when putting the engine together and waiting 12hr before starting.
