What is the compressed thickness of this head gasket?

This Cometic head gasket has a compressed thickness of .045 inches. This measurement is critical for ensuring proper compression ratios and valve-to-piston clearance.

What makes MLS head gaskets different from traditional gaskets?

Multi-Layer Steel (MLS) gaskets are constructed from multiple layers of stainless steel, offering superior strength and resilience compared to single-layer composite gaskets. They are designed to handle the higher pressures and temperatures found in modern, high-output engines.

Does this gasket require any special sealants during installation?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The Viton coating on the outer layers ensures a tight seal against the engine block and cylinder heads.
