The Cometic MLS head gasket for Chevrolet Mark‑IV Big Block V8 (4.375in bore, .032in) combines embossed stainless steel outer layers coated with Viton and an uncoated shim center for customizable thickness. The multilayer design increases strength, resists corrosion and rebounds under load. By spreading clamp load across the sealing area it reduces bore distortion and offers reliable combustion sealing in harsh conditions without additional sealants.
