Cometic copper head gasket for Honda CRX/Civic VTEC engines is specified at 84 mm bore and .043 in thickness and is designed to require less clamp load. The gasket spreads clamp load across the sealing area to reduce bore distortion, does not require sealants or re‑torque, and is intended for engine builds where consistent clamp distribution and reduced distortion are priorities.
