 I have yet to start on a prototype port and chamber but when I do, I will post pictures of the chamber and port as well.  I will post flow figures as soon as I can. So far they look like the next best thing and I am sure beyond all shadow of a doubt that they will be a lot better than the SB2. The port offset is no more than .200 off guide center line so the ports are strait just like a Pro Stock head. No more having to put up with a runner angle opposite to valve cant. I will go out on a limb and predict a peak flow of 450cfm with a 2.180 valve size.
