From Roger Ramjet, Hib Halverson, and SWCDuke on the 2002 Cam.
’02 cam 204/211 degree I/E duration on 116 degree lobe separation, installed 4 degrees retard (events: IO –18, IC 42, EO 37.5, EC –6.5). Valve lift is .551 for I and .547 for E.
The LS6 cam is very different from typical high performance cams. Timing is 12-85/71-33 and the points of max lift are 120/115, inlet and exhaust. These are NOT the "lobe centers" because the lobes are highly asymmetrical.
These disagree a bit , but it should get you in the ballpark
