I'd say replace the CPR but I'm just kinda pondering the hesitation problem. I don't want to say something and be way out of left field so replace the CPR and let us know how the engine is behaving. Your description is pretty accurate. I'm sure with a little more we can figure out the problem. Right now we could try a whole list of things but it really seems as though it's fuel/air related. Hmmmmm, hows the ignition system? Anything new? Also double check the SP Wires to make sure they're going to the correct spot on the Distibutor Cap. I know that sounds a bit dumb because if you can rebuild a distributor you can certainly connect the wires properly. I had a different kind of car perform in a similar fashion when a few of the wires were crossed. Instead of firing in time a spark plug would fire on the wrong stroke which might explain the puffs of smoke and the misfire at high RPMS. I know for a fact a V-6 can run somewhat decent with a "dead" cylinder and it'll really puff along during acceleration. If one of your cylinders isn't firing it would account for the "misfire" and puffs especially in the high RPM range. Also check your appropriate relays and the resistor for the ignition system. Perhaps there might be a clue?? Again, this is just off the top of my head.
