Description

MLX head gaskets feature an extra "stopper" fold-over layer that provides a torque-limiting surface to prevent yielding of the combustion seal.

Proprietary high-temperature coatings and embossments deliver a micro seal to resist fluid leaks between the head and block.

Essential for Milwaukee 8 applications using a turbo, high compression, nitrous, or other power-adder modifications.

No special machining required; these install like a standard MLS head gasket and are engineered for long-term reliability.

Designed to fit air/oil-cooled and twin-cooled heads. Made in the USA. Oil port must be welded and plugged.
