Air bleeds Holley HP (idle & main)

Did some searching but really found nothing that I`m wanting to know... What I have is #72`s in the idle circut and #32`s in the main circut... The problem is the throttle valves have been drilled to 3/32`s to help compensate for a low vac cam (this was for a previous engine with a larger solid roller cam)... When I put it on my engine its to lean... I can cover all 4 air bleed jets and it stablizes almost perfect so I just tried the much smaller #32`s (just switched the mains to the idle and vice vs...) It idles basicly perfect now (except for little or no effect from the mixture screws...?), but I am concered that the main circut will be much to lean... Should I just get another set of #32`s for mains to keep the calibration correct and then play with the idle air bleeds...?

I almost feel like just soldering up the #72`s and drilling them till I get it just right then take note of the drill size and get that size air bleed jet...?
