Yup the bottom of that angle channel is WAY Bigger than the 3310.

I'm can't say if that will make a difference. The channel was never a restriction. The question is whether making it larger than the other passages causes problems - like inconsistances due to turbulance. Ask someone whose played with that stuff. Dominic (thumper) or the guy YR knows.
You can also do a search through RFS forum without joining. I know its come up there. Most are humble and share what we know and ask lots of questions. Don't let that fool ya. Mark W won the carb shootout a couple years ago. Mike Laws was part of BLP, Deep Roots and several others are serious carb builders for racing and restoration...
