Cometic .043" copper head gasket sized for 72mm round bores, intended for Honda DOHC CB750 and CB900 series models from the late 1970s to early 1980s. The copper construction conforms to load distribution across the sealing area, eliminates the need for sealants or re-torque, and requires less clamp load to reduce bore distortion, delivering dependable sealing for older air-cooled DOHC engines.
