The Fel‑Pro valve cover gasket set for Chevrolet small block/302 engines uses Cork‑Lam construction with a metal core bonded to cork‑rubber for improved torque retention and blowout resistance. It provides extra clearance between valvetrain and cover for certain applications. This thicker gasket suits high‑vacuum or demanding sealing conditions and is not intended for emission‑controlled vehicles.
