I have a 2002 M6 Z28 that had about 11,500 miles on it when I had my cam and headers installed. The cam is a Comp 224/.581/114 and the headers are Hooker. They also replaced the pushrods, valve springs, plugs, and wires when they did the cam. They did NOT replace the timing chain, oil pump, or retainers. I asked them about that and they said that since the car had very few miles on it I'd be fine and they'd never seen a broken retainer with my setup. I dynoed 388 RWHP and 371 RWTQ with the above listed mods plus Magnaflow cat-back and MTI lid. I have the stock MAF (de-screened) and FRA. Before the cam I got just over 200 miles per tank and now I get almost exactly 200 (I've pushed it further a few times but I don't like to). Hope this helps!
