Cometic's MLS head gasket for Chevrolet Gen-1 Small Block V8 is a multi-layer steel cylinder head gasket that seals high-output engines without sealants. It fits 4.100" round bores with a compressed operating thickness of .070" and supports 18/23 degree heads. Embossed stainless steel layers with Viton coating resist corrosion and rebound under mixed aluminum and iron mating surfaces, reducing bore distortion and improving load distribution.
