Not Ranked
I think "Zoom This" summed it up pretty good, he found "his" solution the old fashion way, by experimenting. (I'm glad our motors are very similar). The Willy's 62502 (650 CFM HP Carb) can flow way in excess of 650 CFM (like upwards of 750) and has been put on SB's near 427 CID (slightly less) making 650 HP. I spoke to Willy's today and also got a call from my engine builder, they are both in sync with that carb being a real good selection for the 427.
Regarding CNC ported heads, what the engine builder says he has done is match the intake port to the heads. If that's another way to say it fine, if not - then I think what he has done is all that needs to be done for this build 'cause I'm out of money! I will say this, he has done a ton of measuring, balancing, honing and fitting with almost every moving part on this motor.
