Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.540in bore and .065in compressed thickness. Multiple stainless steel layers with embossed outer faces coated in Viton deliver a corrosion-resistant, high-strength sealing surface that requires no additional sealants and resists the shearing forces between dissimilar head and block materials. The uncoated center shim permits thickness variation while embossed layers improve load distribution and reduce clamp load.
