The Cometic MLS head gasket for Chevrolet Mark‑IV Big Block V8 (4.320" bore, .052" compressed thickness) is a multi-layer steel cylinder head gasket that seals combustion and coolant systems without requiring sealants. Embossed, Viton-coated outer layers and an uncoated stainless shim combine to resist corrosion and accommodate thickness needs. The MLS design rebounds and evens load distribution to reduce clamp load and bore distortion.
