 You are aware that Lotusbits already have CNC ported heads, and judging by the dyno plots they are not useless. 280+ BHP from a 2.5l isn't bad...

CNC porting in itself makes no difference in performance to a hand ported head, the advantage comes in the form of repeatability. Once you have a good port you can replicate it infinitely.
