I don't care how good of a programer you may or may not be nothing replaces flow bench and track testing.



totally

But with the proper feedback and the right machinist and or programmer it would be darn close right off the machine.



Are you using a CAD or CAM software for surface modification? If CAM which one? Just curious how you do surfaces with the majority of them (especially a port) being not true geometry.
As far as most CNC porting shops, the way I understand it is they take one hand ported intake and exhaust port (could be great, could be crap)have it scanned and then pattern and mirror it for the head. Doubt they have a CAD user who can manipulate the model to counteract core shift. Maybe Modern can chime in on this.
