The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.100in bore) with a compressed operating thickness of 0.070in is a multi-layer stainless steel gasket built for dependable sealing under high loads. Embossed outer layers coated with Viton resist heat and surface variations; the uncoated center shim provides thickness flexibility. MLS construction seals aluminum heads to aluminum or cast-iron blocks without sealants and helps distribute clamp load to limit distortion.
