Here is a port velocity map. Not bike head. What do you notice about the air speeds?

It looks like your plane of highest velocity starts at the top of the port entrance, angling down to the short side radius? I have no idea what I'm looking at though :whistle:

I noticed the same as Adam, but high velocity area changes sides at the short turn. Is it a twisted wedge head?

Are the much lower velocities at the top of the short turn a result of the valve stem/guide boss blocking the airflow?

That's exactly correct.

The map shows you how quickly and to what extreme the flow pattern can change inside a port.
