The Cometic MLS cylinder head gasket for GM/Mercury Marine 1050 Gen‑IV Big Block V8 is specified for 4.580in bore applications with a compressed thickness of 0.045in. Multi-layer stainless construction with embossed, Viton-coated outer layers and an uncoated shim provides rebound, corrosion resistance and consistent sealing without sealants. The layered design distributes load across the sealing area and reduces the clamp load needed to limit bore distortion.
