The Cometic MLS head gasket for the BMC 1275 A‑Series (.045" compressed thickness, 73mm bore) is built from multiple embossed stainless layers with Viton-coated outer faces and an uncoated shim to meet thickness needs. It’s designed for reliable sealing on 73mm bore BMC 1275 engines. MLS construction spreads load across the sealing area, lowers clamp load requirements, and avoids the need for sealants while resisting corrosion.
