COMETIC Head Gasket - 3 5/8" - .040" C9985

A quality head gasket is the foundation of reliable engine sealing—without it, you're risking compression loss, coolant leaks, and catastrophic engine failure. The COMETIC C9985 uses multi-layer steel construction with load control embossments to distribute clamping force evenly, reducing bore distortion and maintaining superior piston ring seal under extreme conditions. This is the gasket spec racers and professional builders trust when precision and durability are non-negotiable.
