Description

A head gasket failure can cost you an entire engine—and a race. The COMETIC Base Gasket C9988 uses Multi-Layer Steel (MLS) construction with Load Control Embossments to distribute clamping force evenly across the sealing surface, reducing bore distortion and maximizing piston ring seal integrity for consistent power delivery. Built with Viton-coated embossed outer layers, this gasket handles extreme pressures, temperature swings, and varying surface finishes without compromise.

Whether you're running a naturally aspirated or forced-induction build, this American-made gasket delivers the reliability and performance precision that separates winners from the rest.

  • 3-5/8" bore diameter
  • MLS construction
  • Load Control Embossments
  • Viton coating both sides
  • Reduced bore distortion
  • Improved ring seal
  • Multiple surface finishes
  • Harsh environment rated
  • Made in U.S.A.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
