Mr. Gasket Ultra-Seal Valve Cover Gaskets - .312 Inch Thick - 5863 towing-and-hauling 6L/V8 1999 Ford F-250 4Overview: These are high quality gaskets that works well on those hard to seal applications. The low density fiber & rubber blend gasket material seals those minor head imperfections with a low clamp force.
