Is it a noisy port as well?

Something I wonder about is the potential for a hemi's angled intake valve to actually impede flow. It looks like both the inline and hemi heads have similar ports that shoot across the valve, but the hemi's valve back is angled upward slightly into the flow path. A larger valve would make it more so. Just thinking out loud.
No it was not noisy but in the past noisy ports usually was due to turbulence and/or flow leaving short side going around the back of the valve (long side) as a check at max lift or with intake inserted upside down I raise the depression to 40” to listen for noise. Recently I had a head that got noisy and probing with a flow ball could get it to sound smooth but instead of the flow increasing (like it always did before) it decreased. The more you learn about this stuff the more you realize what you don’t know. It is a lot of fun to play with these heads. The hemi has a higher port which is why I like them.
