Product Details

This Cometic High Performance (HP) head gasket is built with a .042 inch thickness and an 87mm bore, specifically chosen to ensure a solid seal for your Honda K20C1 or K20C4 engine. When you're rebuilding the top end or addressing a blown head gasket, getting the right seal is critical for engine performance and longevity. This gasket is designed to handle the pressures and temperatures these engines can generate.

Cometic uses well-built materials to create gaskets that hold up. The precise thickness and bore size are important for maintaining proper compression ratios and ensuring the gasket seats correctly against the cylinder head and block surfaces. This attention to detail helps prevent leaks and ensures your engine runs smoothly after the repair.

For the best results, always refer to your vehicle's service manual for proper installation procedures and torque specifications when installing this head gasket.
