The Cometic MLS head gasket for GM/Mercury Marine 1050 Gen-IV Big Block V8 (4.600in bore) has a compressed thickness of 0.075" and provides a robust multi-layer steel seal suitable for high-output applications without sealants. Embossed stainless outer layers are coated with Viton and paired with an uncoated stainless shim to resist corrosion, rebound under load, reduce clamp-induced bore distortion, and accommodate aluminum-to-aluminum or aluminum-to-iron head interfaces.
