Replacement head gaskets engineered for high-performance applications.
These gaskets use a multi-layer design with a fold-over stopper layer to provide a torque-limiting surface that protects the combustion seal.
Proprietary high-temperature coatings and embossments create a micro-seal to resist fluid leaks at the head and block interface.
Ideal for turbocharged, high-compression, nitrous, and other power-adder builds; no special machining required and installed like a standard MLS gasket.
Designed to fit both air/oil cooled and twin-cooled heads and supplied in matched pairs for common bores and thicknesses.
Manufactured in the USA for long-term reliability and backed by quality control standards.
