Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.540in bore and .086in compressed thickness. Multiple stainless steel layers and embossed, Viton-coated outer layers create a corrosion- and heat-resistant sealing surface that needs no sealants and tolerates aluminum-to-aluminum or aluminum-to-iron mating surfaces. The uncoated center shim allows thickness variation while embossed layers conform to surface finishes and improve load distribution.
