Cometic C8954-018 MLS Head Gasket Multi-Layer Steel - 018

The Cometic C8954-018 is a .018-inch Multi-Layer Steel (MLS) head gasket engineered for high-performance and racing engine applications. Cometic's MLS gaskets are built to outperform traditional composite gaskets in demanding environments where elevated cylinder pressures, extreme heat cycles, and high-boost or nitrous applications push conventional sealing solutions to their limits.

Key Features:

• Multi-Layer Steel (MLS) Construction – Multiple embossed stainless steel layers provide superior sealing pressure and resilience across repeated heat cycles
• .018" Compressed Thickness – Precision thickness allows accurate compression ratio tuning for performance builds
• Embossed Stopper Layers – Controlled combustion and coolant/oil passage sealing without the need for additional sealants on properly prepared surfaces
• High-Temperature Coating – Proprietary coating on sealing layers enhances conformability and prevents micro-leakage on machined surfaces
• Race-Proven Reliability – Trusted by professional engine builders in road racing, drag racing, and high-performance street applications
• Direct OEM-Style Fitment – Engineered to match factory port and bolt-hole locations for straightforward installation

Cometic Gasket has been a leader in precision sealing technology since 1989, offering OEM-quality and beyond for specialty and performance engines. The C8954-018 is recommended for use on properly resurfaced cylinder heads and blocks with a finish of 60–125 Ra microinches for optimal sealing performance.
