Cams for otherwise Stock 5.9 Magnums?

If you read some of the threads over at RamCharger central, several users say that the stock magnum cam specs vary widely according to how a vehicle was outfitted and what level of emissions control class it fell into. I think there are over 12 5.2 cams they've identified with less than .400 lift. Good core for a $159 or so regrind, but useless for any performance usage.
