The Cometic MLS head gasket for Oldsmobile Gen-2 Rocket V8 applications is a multi-layer stainless steel gasket with embossed outer layers coated in Viton and a compressed operating thickness of 0.040". It is designed to provide high sealing performance for classic V8 builds and withstand the shearing forces between differing head and block materials. MLS construction yields improved strength, rebound and corrosion resistance while eliminating the need for additional sealants.
