Mr Gasket - 4404 - Fits 1965-1990 Chevrolet Big Block Mark IV with Rectangle Port Heads

If you want to update just your camshaft and aren't doing a complete engine overhaul, this kit contains all the gaskets needed to change out your camshaft. That way you don't have to buy a complete gasket kit just to change the cam, but still can replace all the gaskets you should in the process.
