Unported head quickness?
I don't wanna come off as a jerk, BUT, it is kind of pointless to not POST A TIME.
This is the whole idea of the thread. To help people go fast without the added expense of porting the head. So if no one knows how fast your going....
The build sure looks tasty though so you should certainly get your butt to the track and let us know how she does. I for one will certainly be looking forward to the results!
