The Cometic MLS cylinder head gasket for GM/Mercury Marine 1050 Gen‑IV Big Block V8 fits a 4.580in bore and has a compressed thickness of 0.036in. Its construction uses embossed stainless steel outer layers coated with Viton and a central uncoated shim, combined with AMP layers for rebound and corrosion resistance. MLS gaskets seal reliably without sealants, tolerate shearing between aluminum and iron, and help conform load distribution to reduce bore distortion.
