The Cometic MLS head gasket for GM/Mercury Marine 1050 Gen-IV Big Block V8 (4.600in bore) is listed with a compressed operating thickness of 0.098" and installs without sealants for a dependable seal in demanding engines. Constructed from multiple embossed stainless layers with Viton-coated outer faces and an uncoated center shim, this gasket rebounds under load, resists corrosion, and evens clamp load to reduce bore distortion when mating aluminum heads to aluminum or cast-iron blocks.
