You need a Dominator. It looks like you spent some money and time on your combination. Now is not the time to skimp.
All the carbs you mentioned above take a TON of work to unscrew. They are far from bolt on.
I would call some non Holley companies and talk to them and spend my money on a custom carb. The initial expense is higher but by the time you fix the junk and waste the time (and money) it takes to fix them you are better off buying a custom carb.
In no particular order:
Baldwin Carburetors (William Baldwin)
Lightning Racing carbs (Mark Whitener)
Thumper Carbs (Dominic)
