The Cometic MLS head gasket for the BMC 1.8L B‑Series (.036" compressed thickness, 83mm bore) uses HP shim technology to improve clamp load around the combustion chamber and enhance sealability for open‑deck blocks. It’s sized for the 83mm B‑Series bore. Embossed outer layers are Viton-coated and the MLS construction helps conform load distribution, reduce bore distortion and avoid added sealants.
