Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8 engines with a 4.060-inch bore and 0.075-inch compressed thickness. Multiple embossed stainless steel layers with Viton-coated outer faces provide dependable sealing without extra sealants. An uncoated center shim permits thickness variation; MLS construction conforms load across the sealing surface, resists corrosion and shearing between dissimilar materials, and requires less clamp load to reduce bore distortion. Viton coating is heat resistant to 250°C (482°F).
