Cometic’s CG head gasket for the Lamborghini Miura V12 (1966–1973) is specified for an 84mm bore with .059 CFM thickness and is identified as the left-side gasket. It requires less clamp load and is designed to conform load distribution across the sealing area, avoiding sealants or re-torque and helping minimize bore distortion under clamped conditions.
