Comp cam XE 274 help

I will be running about 10.75 to 1 compression Keith black domed pistons with ported 714 heads and 1.88" , 1.60" stainless valves, headers , dual exhaust , Performer RPM air gap , 650 cam carb , prepped A500 with stage 2 shift kit , 2800 stall , and 3.91 gears. My builder has built a few of these combos with good results. Not worried about fuel have many options
