66 Valiant 360 Crate motor install

I have recently picked up a 66 valiant. I am trying to put a 360 crate motor into it. I found an article in Hot Rod magazine that makes it look like a 2 day project. Not the case for me. After finally getting the right engine mounts, I have now purchased some headers (doug's). I have them almost in but now am hitting the steering column with 3 of 4 of the drivers side headers. Anyone else run into this problem.
