The Cometic MLS cylinder head gasket for BMC 1.8L B-Series (.040") fits an 83.5mm bore and uses embossed outer layers coated with AMP or Viton paired with uncoated stainless shim layers. Cometic engineers gaskets to rebound, resist corrosion and distribute clamp load evenly. The MLS construction installs without messy sealants, requires less clamp load to limit bore distortion, and suits a range of engine builds requiring reliable sealing.
