They are race only cams. They do not include the small cam lobes, only the large "VTEC" lobes. The cams don't do a damn thing until 5,000 rpms and have a very high peak. You need to remove the stock rocker assembly. Check out www.todaracing.com for VTEC killer cams info under the B series products. Definitely a waste of money unless you're building a race car.
