I guess is what I'm trying to say is that the CNC program that is used to profile the heads I'm sure has been researched and pretty close to the best you can buy. IMHO.

I think unless you have spent time with one of these engines you don't realize how good the parts are that used in these engines.

I've seen inside a few, whether good parts/execution were used is likely a matter of opinion, to each their own.
