I stopped porting at 267 in my first intake port.
Starting on my 2nt intake port with some new idea.
Cutting in the 2.02 w/nail head valve, netted me 21 cfm at .500" after i put a nice 3 angle cut to the seat it brought my .100" cfm up from 57 to 77 cfm.:cheers:
So there's a lot to be gained just by cutting in a 2.02" and having a 3 angle valve job done to it, while i'ts at the machine shop getting rebuilt.
then if you want more,.... smooth and round every thing in the port.................From there you real need a flow bench to know what works and what should have!..... but killed the flow.:angry7:
Just my 2Cents :-D
