Modern Cylinder Head

CNC doesn’t mean good, nor does it mean that the copied port was any good.

I’ve seen lots of junk CNC heads. Personally the best OOTB CNC heads I've seen is the TF small block heads. I haven’t flowed one, but it’s the best CNC porting I’ve seen.
That's why the research needs to be done before the cnc programing. I know everyone was sending there predator heads to them and selling them as there's. I not sticking up for them just telling what I know. They always had a good replication. I hope they have kept it.
