the second is their 383 with the Callies upgrade

My question is, is the Callies upgraded 383 worth the 300 extra dollars? The parts going with the motor aside from the rotating assembly are a MS4, FAST90/90, PRC 5.3L 2.5 heads(i know the heads are some what of a limiting factor) and a 100-150 shot from a TNT F2 kit.
P.S. current mods in sig.
