The Cometic MLS head gasket for Chevrolet Mark‑IV Big Block V8 (4.630" bore, .095" compressed thickness) is a multi-layer steel cylinder head gasket that seals combustion and coolant passages without additional sealants. Its embossed outer layers use AMP coating while an uncoated stainless steel center shim controls thickness. MLS construction rebounds, resists corrosion, requires less clamp load and evens load distribution.
