The Cometic MLS cylinder head gasket for BMC 1.8L B-Series engines is a .070-inch gasket sized for an 83mm bore. HP shim technology increases clampload around the combustion chamber to improve sealing; embossed outer layers and an uncoated stainless center shim manage load distribution while reducing required clamp load and bore distortion. Both sides are coated with Viton for chemical resistance.
