Thanks for the kind words! I like it that I can port all the current '02+ heads the same style.

I have not flowed the heads since the last flow numbers posted in the thread. Flow numbers vary slightly head to head depending on the valve job done and valve size. My flow numbers from the start was all on stock valves using the stock cams to open the valves. There was actually one head that was flowed with +1mm valves and porting work. The link can be found in the first post. I don't think we actually came close to getting the full .400" lift but as far running stock cams, that's how much more gains you have. You can expect more flow with performance cams.
