Addressed below.

I'm toying with the idea of making a custom manifold for my ITB project, but obviously I won't have a lot of these same problems...

Honestly if that's what I have to do, that's what I have to do. As it stands I'm trying to avoid doing it so I can have a much more compact set up. It would also eliminate the ninety degree bend that everyone has right in front of the throttle body (can we say pressure drop?). I'm still massaging it a little bit, and I'm confident that I'll be able to get it to flow right with the current thought/process (I have pretty much the entire summer to do it).
