The Cometic MLS cylinder head gasket for GM/Mercury Marine 1050 Gen‑IV big block V8 (4.500in bore) carries a nominal .072in thickness and includes two slotted lifter valley bolts. Its embossed stainless steel outer layers are coated with Viton, giving corrosion resistance and rebound. The multi‑layer design seals aluminum-to-aluminum or aluminum-to-iron interfaces without sealants and evens clamp load to limit bore distortion.
