CNC Mill Mark Removal in Intake Port

As velocity goes up, surfaces can be smoother.
What are your thoughts on going smoother (like 120 grit or more) to see if there’s any noticeable effect on flow numbers…fuel mixing concerns aside. My thinking is along the lines of a high revving stroker, where the velocity is actually there to induce mixing vs chuffing around on the streets. I know your next post mentions the oversized aspects of the port, so there may not be much else you can do without touching the valve and seat.

Thank you again for all the testing and info you provide!
