There CNC version of anything is a waist of time. I talked to them about a year ago about a set of small block Chevy heads I had here for a customers engine. The guy said all they do is map a stock port and add .010 to it. Just enough to show they were CNC's all the way through.

I will look at the SBM heads for a budget 340 I am thinking about doing for my Dart.



That would be the first time I've heard that... most
shops that CNC they do a hand porting based on the
flow then read it to a CNC program.... but maybe that
company does that crap




Maybe they should've stolen the design from a ported Edelbrock, not one OOTB.
