Missed on this combo?
Love you Jim because you're honest. Sorry for the cussing but when I get real revved up about something I am 100% confident in-it happens. Cracking an honest 600HP is VERY difficult if not impossible. I know this is getting off track here but this engine is pretty decent as it is. It is soft down low which tells me retarding the cam ain't gonna help Jack and the engine will never recover up top--it doesn't work that way hardly ever. I can tell how good a dyno run is going to be as soon as that initial torque number rolls in. I abort many runs as it is a waste of fuel/time and motor if it doesn't look good right away. J.Rob
This will probably lend more credence to your cylinder head theory. My cam isn't that much different from what Mike is running..........

Yet the dyno results are markedly different. You can't race dynos, but this is my dyno, and we do calibrate it. This is the one and only pull we started at 2,500 rpm.

I agree that Mike's engine is pretty good, and I think probably better than most. It could be even better.
