Cometic dead-soft copper head gasket for BMC 948/1098 A Series (67.5mm bore) in .063in thickness is intended for engines already machined for steel o-rings and extreme cylinder pressures. The fully annealed copper compresses easily at installation, conforms load distribution, and reduces the requirement for sealants or re-torque while helping to minimize bore distortion in high-pressure combustion environments.
