I'm not sure how close to the chamber wall your intake valve is in those pics, but they make a nice adjustable cutter tool to "sweep" with, makes it super easy to un shroud the valve, and make them all consistent.

Ya I’ll double check a few things tomorrow after I probe for air speed. My old open chamber heads on the car now went 318cfm. My bore adapter is only 4.015 so that doesn’t help either. I do know that 10-15 degree top cut helps the piss poor chamber on these heads but I wanted to see what just the cutter did. I have a Neway cutter for that job.
