Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.540in bore and .070in compressed thickness. Multi-layer stainless steel construction with embossed outer layers coated in Viton yields a resilient, corrosion-resistant seal that requires no sealants and tolerates aluminum-to-aluminum or aluminum-to-iron mating surfaces. The uncoated center shim permits thickness variation while embossed layers conform load distribution and reduce required clamp load.
