Have you ever had the heads on a flowbench? What kind of cranking pressure (cylinder pressure) do you have? I'm asking because I think that your cam is a little too big. Shorten up that duration (and tighten lobesep?) and you've got valve clearence. What have you got for header dia? length?

Lets see...
There are two intakes listed. (3698431 and 3698437) Ill have to try and find the one ending in 7.

Heads. No flow bench

180psi cranking pressure

Headers are 1.50 dia with 3' out. Not sure of length but has 12' collector
