COMETIC Head Gasket - 4"- .040" C9880

A head gasket failure can sideline your engine and drain your wallet—this is where precision engineering becomes non-negotiable. The COMETIC C9880 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. Built to handle aggressive boost pressures, extreme temperatures, and demanding surface finishes, this U.S.-made gasket delivers the reliability that serious racers and high-performance builds demand.
