This is a high quality gasket that works well on those hard to seal applications, the extra thickness and rubber coating helps to seal those minor head imperfections. These gaskets are ideal for all those high performance applications where you take the valve covers off and on a lot, and sticking is a problem.


  • These Are A Cork Rubber Blend
  • Extra Thick 5/16 In Creates Positive Seal
  • Also Available In Standard Thickness
  • For OE Replacement And High Performance Apps
