happy you talked to Bob K. something to try but don't forget where you started from incase you end up being happier where it was. i would open up the center carb 2 1/2 turns on both idle screws. then turn in the idle screws one at a time checking as you go while covering the air bleed and checking for a rpm change. if the rpm drops, richen the mixture, if rpm increases, lean the mixture. do thse one at a time and when you are done do it again. after you are happy that there is no change in rpm, the using a vacuum gauge adjust the idle on the center carb. then check it again. all this is assuming that the timing is setup where it needs to be.

this is how my car is setup and i think it is running pretty well. all i can say is try it and if it does not work out, change it back to the way you have it now. you did say you think it is running better since you took the advice of mr sixpack. personally i would rather take the advice of mr sixpack over a holley "tech" any day. if you don't mind me asking, what advice did you get from mr sixpack that helped you out?

i would double check all the float bowl levels. center just to the bottom of the hole and the outboards flowing out. if the plug was still there it should be half way up the hole. this is important!! if that is all set then i would take and give an extra 1/8 turn to all the outboard idle screws. take it for a ride and see what you get. now it is a matter of doing one thing at a time and see what the results are. seems like you are really close.
i don't remember, what is your timing at? initial and total mechanical and what rpm is it all in.
