MLS head gaskets promote an even torque load across the gasket sealing surface, providing less bore distortion and better piston ring seal for more power. 4-stroke head gaskets are made to perform on today’s highest-output 4-stroke naturally aspirated and boosted machines, utilizing a multi-layered steel design with the outer layers being embossed and coated with a Viton rubber coating; these head gaskets are designed to meet the demands of today's high-horsepower, high-cylinder-pressure engines.
