Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8 engines with a 3.910-inch bore and 0.120-inch compressed thickness. Multiple embossed stainless steel layers with Viton-coated outer faces provide robust sealing without additional sealants. The uncoated center shim allows thickness customization; MLS construction conforms load across the sealing area, resists corrosion and shearing between dissimilar materials, and requires less clamp load to limit bore distortion. Viton coating is heat resistant to 250°C (482°F).
