Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8 engines with a 4.130-inch bore and 0.045-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 customization; MLS construction conforms load across the sealing surface, resists corrosion and shearing between dissimilar materials, and requires less clamp load to help limit bore distortion. Viton coating rated to 250°C (482°F).
