Need Quick Fuel carb tuning assistance

I have Edelbrock heads. Cam is comp cam xe275hl ( [email protected] with .525 valve lift intake and exhaust.( 411hp at 5700rpm) Just this morning I set the front Tslot to .040 exposure and opened the rear butterflies to just a little under the rear Tslots (almost perfect) I started the engine got it hot (195* tstat) and have been running 1/2 turn in all four corners, I had to open them up a little over 1/8th turn. Also dropped the pump shot from 31 to 28. Idle is at 850 rpm. Just by the way it idles and blipping the throttle I think I am headed in the right direction. You are right about the timing at 20*, those cylinders are hitting hard and it wants to jump up and down in low gear when taking off if not clutched right, especially with the grabby centerforce clutch.The autolite Ar3924 spark plugs I use are the equivalent to the champion RN12YC.
