Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.375in bore and .120in compressed thickness. Built from several stainless steel layers with embossed outer faces coated in Viton, it offers a corrosion-resistant sealing solution that requires no sealants and resists shearing between aluminum and cast iron or aluminum components. The uncoated center shim supports different thicknesses while embossed layers improve load distribution and reduce clamp load.
