5.9L Magnum build with questions

Nice build, but your not gonna make peak power in the 6000 - 6500 rpm range. You would need a lot more head for that. Probably be in the 5400 - 5600 rpm range.
I’m not following you? I haven’t even gotten my heads yet to know the flow numbers on them. My cam is supposed to make power past 6,200 and rev near 7,000.
