The Cometic MLS head gasket for the BMC 1.8L B‑Series (.060" compressed thickness, 83mm bore) uses HP shim technology where noted to increase clamp load around the combustion chamber and improve sealability on open‑deck blocks. It’s specified for 83mm bore B‑Series applications. Outer embossed layers are Viton-coated and the multi-layer design spreads load, reduces distortion and provides reliable sealing without added sealants.
