The Cometic MLS head gasket for GM/Mercury Marine 1050 Gen-IV Big Block V8 (4.600in bore) is specified at 0.120" compressed thickness for builders needing increased shim depth and installs without sealants. Made from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated center shim, the gasket resists corrosion, rebounds under load, and helps distribute clamp forces to reduce bore distortion across aluminum and iron head interfaces.
