Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.540in bore and .080in compressed thickness. Built from several stainless steel layers with embossed, Viton-coated outer surfaces, it provides a corrosion-resistant seal that requires no additional sealants and copes with aluminum-to-aluminum or aluminum-to-iron applications. The uncoated center shim supports thickness variation while embossed layers conform to finish and distribute clamp load more evenly.
