Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.375in bore and .070in compressed thickness. Multi-layer stainless steel construction with embossed outer layers coated in Viton provides a high-strength, corrosion-resistant seal that requires no sealants and tolerates aluminum-to-aluminum or aluminum-to-iron mating surfaces. The uncoated center shim allows thickness variation while embossed layers conform load distribution and reduce clamp load.
