New Hemi Swap with Borgeson Steering Box?

I talked to Sam from TTI and he said the headers are identical to the other one except for the 1-3 tubes. He really didn't think there was a problem, but admits the mock up and display K member was biscuit andthat could be the problem. I don't know what to do, they didn't say "send them back, we'll take care of it" instead I got "try it and send pictures of what you figure out". I'll decide when they're in my hands.
