Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8 engines with a 4.060-inch bore and 0.140-inch compressed thickness. Multiple embossed stainless steel layers with Viton-coated outer faces deliver dependable sealing without extra sealants. The uncoated center shim allows thickness adjustment; MLS construction conforms load distribution across the sealing area, resists corrosion and shearing at dissimilar-material joints, reduces clamp load needs and helps limit bore distortion. Viton coating rated to 250°C (482°F).
