I may have just got lucky with port timing and such on it since I did nothing scientific really, just a few measurements and guess work with some calipers, some filing and some dremel work, I had planned to take the deck height down some, but then just decided to see how it would run without changing it.
That's one good thing about reading in the forums for porting, a lot of people post the "if you cut up a milimeter here, down a milimeter there, go this much wider here, and clean out this area" you can actually get a nice fast engine with good power without all the calculations... If you go back and measure everything when it's time to rebuild it I bet your timings and durations are really close to what we've been talking about a lot these last few days..
