I am really hesitant to drop it back in - regardless as if I change the gear (which I think is a given).
The DUI is plug and play, no doubt, but you already have an HEI. I'd just get a good gear and roll with it.
There's no point in going back to a stock unit....you'd have to buy all the parts, undo whatever the previous hacks have done to the wiring, and then tune it and tune it, just to get even with the performance the HEI will give you.
If you didn't have the HEI already, maybe that'd be worth the trouble, but that's not the case.
I agree that it sounds like a case of one of the old hardened gears showing up. Also agree with checking how the gears mesh, since you have it apart.
It'd be interesting to know what brand an HEI that is...Ebay, Summit, 4 Wheel Parts, CRT, etc. And how old that one is, e.g., when it was made.
Sounds like you're on track to get it right, though.
