Just looking at them I would have to say yes. There are no interruptions (besides the boosters) in the bores to the left where the Holley looks like a yard sale on the top of it. Left also looks like a smoother transition from the booster to the plate. The throttle plate itself looks to have blind screws.
What about these two 1.58" v HP-style bodies that both have .600" ID 12-hole annular boosters? Do you see 20 CFM difference in flow between them?
