The Cometic MLS head gasket for GM/Mercury Marine 1050 Gen-IV Big Block V8 (4.600in bore) offers a 0.066" compressed-thickness multi-layer solution for high-output engines. It seals reliably without sealants and includes two slotted lifter valley bolts where specified. Constructed from embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless shim, the gasket resists corrosion, rebounds under load, and evens load distribution to reduce bore distortion across aluminum and iron interfaces.
