The Cometic MLS head gasket for Chevrolet Gen-1 Small Block V8 (4.060in bore) with a compressed operating thickness of 0.036in is designed for demanding sealing conditions. Multiple embossed stainless steel layers with Viton-coated outer faces provide heat-resistant sealing without sealants. The uncoated center shim permits thickness variation; MLS construction handles dissimilar metals, spreads clamp load and helps limit bore distortion in high-output engines.
