    What are the benefits of this, why is it done, and how is it done? I've seen people talking alot about this and I just don't want to be in the dark about it anymore.

    re-grinds suck.

    basically, they add material to an existing cam, and then re-cut it.

    The bottoms are grinded also to adjust the valve lash up closer to the shaft for more lift, and to change duration!

    i had a friend that would die before he said regrinds were bad, yes they CAN be bad for valve train, but NOT always, if done right they make alot more power, cost alot less than full cams, and are perfectly safe to run. all they do is grind ur stock cams, to give u more aggresive cams, therefore making more power. i think they are good but only if done right.

    Example, my friend had a 1990 Civic Si, with a ZC, with i/h/e. ran 15.1 fully gutted. Took his cams to Colt Cams, got them ground, and after that ran a 14.6. he drove on them for a year before he sold the engine and got a b18c5, and never had a problem
