That's pretty good! Must be ~650 FWHP... and that exhaust has to be costing at least 50 hp - I bet more like 75-80. It would be interesting to know how well those lifters hold up.
I've been looking at the ports on my intake and can see that I'm going to be in the same situation -- against the pushrod tubes and still not as wide as the ports on the heads.
