The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.100in bore) with a compressed operating thickness of 0.051in is a multi-layer stainless steel gasket designed for demanding sealing tasks. Embossed outer layers coated with Viton resist heat and harsh sealing environments while an uncoated center shim provides thickness flexibility. MLS construction seals dissimilar materials without sealants and helps distribute clamp load to limit bore distortion in high-output engines.
