Cork-Lam is used for applications where high-vacuum or blowout conditions can be a special problem
Cork-Lam uses a metal core with cork-rubber material chemically and mechanically bonded on both sides providing a thicker-than-normal gasket with exceptionally good torque retention
Allows additional clearance between the valvetrain and the valve cover
Not intended for use in emission controlled vehicles
