Fel-Pro Valve Cover Gaskets - Big Block Chevy with Big Chief/Super Duty Heads - Cork - 1/4"
Certain engines, such as small block and big block Chevys, can produce high-vacuum or blowout conditions that can be big problems for many valve cover gaskets. Fel-Pro Performance CorkLam gaskets are designed to deal with those challenges. They have a metal core for extra strength, with a special cork-and-rubber compound bonded to both sides. This produces tough gaskets that can deal with problem engines, while also providing a little extra clearance between the valve cover and the valvetrain.
Fits all with Super Duty Pontiac/Brodix or Dart Big Chief Heads. 4 upper and 4 lower bolt holes including Pro Stock applications. Cork-Lam construction utilizes a metal core with a cork-rubber material chemically bonded to both sides.
