Cometic head gasket in JB custom specification reduces required clamp load while promoting even load distribution across the sealing area. The construction minimizes bore distortion and eliminates the need for additional sealants or re-torque in typical use. These traits make it suitable for rebuilds where predictable clamping and stable sealing are priorities for maintaining engine integrity under higher cylinder pressures.
