Indy Motor Swap

I just found a nice 69 Dart as a prospect to put my Indy 440 Engine into. Can anyone advise me on what surgeries will need to be performed on this car? The car is sporting a 360 now. Will that K member be the same for the BB? I am sure there is going to also be a header problem. Most of the Darts that I haver seen with BB's have those funky looking headers that have to be routed thru the inner wells. Will there be a need for a "specialized header" since I am using Indy heads? Thanks alot for your help
