Quote: isn't it proven by jeff at modern that his cnc program on 906 heads outperformed a hand porter on a FAST build getting a 440-6 RR into the 10 second zone while the hand porter was only able to get the A12 RR to low 11's. i believe thats proof enough that CNC'ing one of these heads works better then hand porting. if i were to do it again CNC'ing is my choice,hands down.
A 10sec pass so far has only happened ONCE , Ed had a killer 60ft and has not been able to duplicate it since .
You should stick to what you know ... BBQ'ing skirt steaks ...
