I have started doing my own porting as the guy I've been using is not porting right now. Hopefully he will get back going someday. That being said hand porting will work as well as cnc if done by someone who knows what they are doing but it is a time consuming process. I have a set of Dave Wilcox ported iron heads that have outflowed many cnc ported versions of the same head on the same flow bench. Hand porting will get you there just find someone willing to take the time. Unless you are looking to increase the performance on a restoration or a stock looking combo aluminum heads are better option anyway. I have 3 sets of ported iron heads I will actually probably only use one set on my own car but I don't mind grinding on the iron ones as a hobby would not want to try and make a living doing them. Good luck to Dave and I understand his logic in this process and we thank him for all of his support to our hobby.
