Those headers might be tricky to find for that narrow frame.
Either some shorties or stacks out the hood.
I have mine dump out the fenderwell & there were no clearance issues. One truck was a '77 F150 with 38" tires and the other was a '79 F250 with 33's.
I think you should come get my old 400. The EGR bumps have already been removed, mild port/polish, and a valve grind that you won't see unless you work in a race shop.
