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.
