The carb is probably not the most pressing issue. What intake manifold do you have to go with it? I assume you have a SB hood, or you wouldn't have the issue.
Not really a clearance issue right now as I have a BB hood, it’s just I want to maximize air flow. And I heard a rumor of the low profile 700 cfm carburetor but can’t find anywhere
If you don't have a clearance issue, why do you care? You can always buy a drop-base air cleaner which will lower the upper cover by about 2 inches or so.
If you still have a spread-bore intake on the engine, stay with the Q-jet. 750cfm and lots of benefits. The carb does need to be rebuilt and set up properly (as would ANY carb you choose).

Q-Jets and all the Holley-based designs are all the same height. There is no "low profile" carb that is going to gain you any hood clearance over any other carb.
