Need advice on setting T-sync on 4 corner idle carb

I have a 750 with the 4 corner mixture screws and no PV in rear. Carb is out of the box stock. On my old Holley without 4 corner, I set the front T-slots and left the back alone. My question is on the new carb, do I set both front and rear slots the same, see where my idle is and adjust front and rear idle screw equally to bring idle where it needs to be? Or leave the back alone and just set the front like my old carb. Thanks FABO!
