The Cometic MLS head gasket for GM/Mercury Marine 1050 Gen-IV Big Block V8 (4.600in bore) provides a durable multi-layer sealing option for high-output engines. It installs as a direct gasket and is specified with a compressed operating thickness of 0.098". Built from multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated center shim, the gasket rebounds under load, resists corrosion, and suits aluminum-to-aluminum or aluminum-to-iron head applications without added sealants.
