The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.100in bore) with a compressed operating thickness of 0.023in is a thin multi-layer stainless gasket intended for high-output engines. Embossed outer layers coated with Viton provide heat-resistant sealing while the uncoated center shim permits thickness adjustment. MLS construction seals aluminum and cast-iron combinations without sealants and helps manage clamp load distribution across the sealing area.
