Choosing cam for 5.9 magnum

I am not sold on reground cams unless you absolutely are having a hard time finding a new one for an odd application. My buddy just got the 5.9 in his 01 ram sorted out after a Hughes regrind failed. It flaked out bad on the ramps and base circle where the material was mostly removed, the lobes actually looked fine on top. He was made right and upgraded to the next biggest on a new core. So far so good. That truck has the Hughes airgap, big gulp throttle body, the matching Hughes springs/retainers/locks, and now eq heads since it had one end cylinder on each head Crack between the seats.
