What size carb should you use on 350 Chevy LT1 with 202 heads?

most 202 valve heads have a 205cc intake runner,the old hot rodder rule,was to multiply this by 4 so 205x4=820cfm.with out being over carbed.so long as you have the exhaust flow open good.a respectable cam.and good ignition fire.i my self like a 750 dbl. pumper holley for this combo.keep in mind this,edlbrock builds good manifolds.but holley builds great carburators.
