Quote: IMO a god head porter can get the most out of any individual head IMO. As pointed out where do you think the original port design for the CNC was digitized from?? CNC work is fine for mass produced stuff. But ask how many with CNC'ed Indy or b1 stuff have epoxy in them due to core differentiations? One size fits all is rarely what I am looking for in life, just saying.
True. But with the designing and CAD software's out there, custom CNC porting per an individual head is certainly doable.
The guy I use does hand porting and also does aluminum head repair. Last time I went there he had CNC'd B1s to repair, core shift was bad enough that that the CNC program broke through in a spot. Wouldn't have happened if a competent hand porter did the port work.
