JMHO.....from looking at the picts of the motor I would guess that the finish is OEM. The black on the plenum looks to be a bit better than the black on the cam covers, but it could be the angle & light.....to me the give away to stock paint is the pox up at the T/B plate in the close up pict of Gordon's & Chris' signatures.
Also, my take on the brakes is that they are not in this picture group. The fronts look stock to me? The rears are for sure OE.
Eric, I would ask a favor from JVD and ask him to call that dealer and see if a bit of professional courtesy could be leveraged to get some answers to your Q's......worth a shot, no?
Good hunting!
