Not sure, I've always heard if port design allows it at the throat should be mcsa, but since many ports don't push rod pinch is generally where mcsa happens, I'm like you on this I'm just a learning, I also want to build a bench.

I think some of my assumption stems from the fact the bowl sides tend to be angled so at the bottom, its going to be narrower than at the seat.
