According to the specs, the Civic-R camshafts are slightly different from the Integra Type-R camshafts. Actually the difference is only on the intake side. The VTEC lobe on the intake side has slightly more duration (3 degrees more compared to the Integra Type-R) and the cam profile is bigger and broader. The exhaust cams are exactly the same as the Integra Type-R.
