The Cometic MLS head gasket for GM/Mercury Marine 1050 Gen-IV Big Block V8 (4.600in bore) is a multi-layer steel sealing solution engineered for high-output marine and performance engines. It delivers reliable sealing without additional sealants and includes two slotted lifter valley bolts for proper installation. Constructed from embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless shim, this .045" compressed-thickness gasket resists corrosion, rebounds under load, and helps distribute clamp forces to reduce bore distortion.
