If you can get hold of a copy of David Vizards book "Tuning BL A series engines" its well worth a read. He did a whole series of flow bench tests whith various configurations of flat edges, radius etc and it clearly shows that the shape at the edge of the intake is critical to the airflow peformance.

That book is a blinking good read. It helped me many years ago when i was tweaking my mini.
One thing i learnt was the different shapes of belmouths and the effect they can have on engine performance.
