if you go to figure out how much carb you need for an engine the formula is something like... (Engine displacement X Max RPM) devided by 3456 and then take that answer and multiply it by the engines efficiency witch on an engine that isnt forced induction and street should be around 85% or .85 after that formula you should know roughly what CFM carb you need....

i hoped that helped a little.... if it runs better with a larger carb then the smaller one or the one ment for it wasnt tuned right and needed bigger jets

I'd get your exhaust done before worrying about tuning it to run right. Open headers don't give you the back pressure your engine needs to breath correctly. Once your exhaust is on, then see if it's flooding out.
