The Cometic MLS cylinder head gasket for GM/Mercury Marine 1050 Gen‑IV Big Block V8 suits 4.580in bore applications and has a compressed thickness of 0.030in. Constructed from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated center shim, it provides sealing endurance between differing materials without sealants. The layered design rebounds under load, resists corrosion, and helps distribute clamp load to limit bore distortion.
