Cometic C10092-045 MLS Head Gasket

The Cometic C10092-045 is a high-performance Multi-Layer Steel (MLS) head gasket engineered for demanding engine applications. Cometic Gasket is a globally recognized manufacturer of precision gaskets trusted by professional engine builders and performance enthusiasts alike.

MLS head gaskets feature multiple layers of embossed stainless steel that provide superior sealing capability over traditional composite gaskets, making them ideal for high-compression, forced-induction, and high-horsepower builds. The .045-inch compressed thickness (as indicated by the -045 suffix) allows builders to fine-tune compression ratio when combined with milled heads or aftermarket pistons.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum sealing integrity
• .045-inch compressed thickness for precise compression ratio tuning
• Stainless steel embossed layers resist combustion pressure, coolant, and oil
• Designed to withstand high-horsepower, high-compression, and forced-induction environments
• Precision laser-cut bore openings for accurate fitment
• Reusable surface coatings for improved conformability to machined surfaces

Cometic MLS head gaskets require a proper surface finish on both the block deck and cylinder head (typically Ra 45–125 micro-inches) for optimal sealing. This gasket is a direct replacement or performance upgrade over OEM composite units, offering improved longevity and reliability in race and street performance applications.
