41mm valves is alot of valve for such a small port.
I don't have a tach or anything, and I don't have my dyno sheet here at school with me, but it does idle very low. I call it my "single cylinder cummins" since its such a low revving motor. I got the head straight from Rob Barnum, who builds them for drag racing. We can speculate how it will run, but until I do, all we have is theories, and I trust him as a motor builder. I'll still have a stock head as well so I can do a comparison.
The biggest advantage of the setup I run is its weight. Its got gobs of power, but it weighs less than my 400ex does. I'm by no means a small guy, at 235 lbs, but the bike doesn't weigh as much as a raptor, which contributes a lot to how fast it is.
