Alot of people have told me to leave the 1bbl on for a variety of reasons,choke/choke p/o,linkage problems,trouble with the kickdown,and hesitation on full throttle pulling off the line
Those people are ignorant, careless, and/or incompetent. If you have all the right pieces, there'll be no such problems. A carburetor in good condition is of course necessary for the engine to run well, and "remanufactured" carburetors usually don't work well.
I would like to have the 2bbl for the extra power,and the smoother running engine
So? Is it your car or is it an investment? If it's an investment you're in for a harsh surprise when you try to make back even a fraction of what you've put into it. I imagine it's your car, so carry on improving it as you will. Besides, we're talking about bolt-on items here. If suddenly we find ourselves transported to a universe wherein slant-6 A-bodies are worth Duesenberg money, then you can swap back to the 1bbl setup.
