Cometic C8927 MLS Multi-Layer Steel Head Gasket - 030

The Cometic C8927 is a .030" (0.76mm) Multi-Layer Steel (MLS) head gasket engineered for high-performance and competition engine builds. Cometic's MLS head gaskets are constructed from multiple layers of embossed stainless steel, providing superior sealing integrity under the extreme cylinder pressures and temperatures found in modified, turbocharged, supercharged, and naturally aspirated performance engines.

MLS head gaskets require a properly finished head and block deck surface for optimal sealing. Cometic recommends a surface finish of 50–125 Ra for best results. This design eliminates the traditional composite core, making it highly resistant to combustion blowout and coolant or oil intrusion — a critical advantage in high-boost or high-compression applications.

Key Features:

• Multi-Layer Steel (MLS) construction — embossed stainless steel layers for consistent, reliable sealing
• .030" compressed thickness — allows precise compression ratio tuning
• Withstands extreme cylinder pressures from forced induction and high-compression builds
• Resistant to combustion gas, coolant, and oil leakage
• Compatible with aluminum and cast iron cylinder heads and blocks
• No retorque required after initial heat cycle
• Manufactured by Cometic Gasket — an industry leader in precision gasket technology

The Cometic C8927 MLS head gasket is an ideal choice for engine builders seeking a premium sealing solution that delivers consistent performance in demanding applications.
