Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.540in bore and .056in compressed thickness. Constructed from multiple stainless steel layers with embossed, Viton-coated outer layers, it provides a durable, corrosion-resistant seal that requires no sealants and tolerates aluminum-to-aluminum or aluminum-to-iron pairings. The uncoated center shim supports thickness variation while embossed layers conform to surface finishes and distribute clamp load.
