Cometic MLS cylinder head gasket for Chevrolet Mark-IV Big Block V8 with a 4.375in bore and .089in compressed thickness. Multiple stainless steel layers with embossed, Viton-coated outer layers provide a heat-resistant, corrosion-resistant sealing surface that requires no sealants and resists the shearing forces between differing head and block materials. The uncoated center shim allows thickness variation while embossed layers help distribute load and lower clamp requirements.
