One ported one 90% done

Looks great. I have to ask and I think you have mentioned the number before but, what percent of gain is after the valve job and bowl blending?
If my memory is correct, just the valve job and bowl blend was 80% of the gains on a 2.02 valve stock type heads.


Man that number is buried back in our Speedmaster posts somewhere. I know the porting work pays dividends from .300-.550 even with a 2.02 as the port becomes smoother.
