I'd say go with the early style with manual choke on the center carb. Don't hook up the chokes on the 2 outboard carbs, you won't need them.
I will say that I go along with Carb King. I don't care much for the Rochester either. Seen too many of them either have cracked float bowls or warped bases. Or both like the one that was on mine. Carters are OK, as long as they're matched. Been ther, done that. Got mismatched carbs from the remanufacturer (one was a FORD carb). Now running matched Holley 1904s, IH application (GMC used them too), very happy with them.
