The Cometic copper cylinder head gasket for BMC 948/1098 A Series (67.5mm bore, .043 in.) uses fully annealed dead-soft copper construction to provide a compressible sealing surface that conforms under clamp load. Copper gaskets are intended for engines machined for steel o-rings and offer uniform load distribution, reduced bore distortion and fewer sealant or re-torque needs compared with other types.
