Hands down the Rochester Monojet is the best bet .

'68 ~ '72 (I think) has very little in the way of controlled bowl vents etc. and is available with manual choke, some of them I have seen converted to manual choke from automatic .

RockAuto.com sells them from some Mid Western place that has amazingly good cores .

Unless you can wobble the throttle shaft noticeably in the idle position, it's hard to imagine it being worn out .

Most "Carburator problems" are in fact, electrical so move slowly and never, EVER let go of your old core part until the job is 1,000 % finished to your satisfaction .

EVER .

As far as HEI dizzies, the GM ones don't look fancy but are stellar in application ~ the one I bought from a clapped out 1977 Nova Coupe was nasty looking and badly worn in the flyweights and springs etc., I used good used weights from a V8 dizzy that had the same #'s stamped in then plus new plastic slides (important, you'll understand as you take it apart) and springs .
