The Cometic MLS cylinder head gasket for GM/Mercury Marine 1050 Gen‑IV Big Block V8 fits 4.580in bore applications and has a compressed thickness of 0.086in. Its multiple embossed stainless layers are coated with Viton for heat and corrosion resistance, and an uncoated stainless shim allows thickness variation. MLS construction seals reliably without sealants, resists shearing between different materials and helps conform load distribution to reduce bore distortion.
