TTI Header help

I happened upon TTI headers part number 636A with the exhaust system less the mufflers for a decent price so I bought them. They are for early a-body small block 63 to 66. My question is, do you think they would work on a 1968 Dart GT, small block 360 with aluminum Edelbrock RPM heads, 833 4 speed, no power steering, factory K-frame? I called TTI and all they could say is that they are for the 63 to 66 a-body. I have not found any information about this, and hoping someone on here may know for sure. Anyone I have talked to have said they can't see why they shouldn't work. My engine is out at the machine shop right now so I can't even try and mock them up.
