The Cometic MLS head gasket for Chevrolet ZL1 Mark-IV Big Block V8 (4.375" bore, nominal .098") combines embossed stainless steel layers with Viton-coated outer faces for robust, corrosion-resistant sealing. Its multi-layer design handles mixed head and block materials without sealants, resists shearing and rebounds under load. The uncoated center shim allows thickness adjustment to reduce clamp load and improve sealing across the combustion area.
