Doug's Headers installed with some clearance issues

So I finally got back out to the garage to continue working on this issue since I would like to be driving the dart now. It appears that the engine is centered in the bay, so i need to move it to the passenger side 1.25". I've been using a couple small wood blocks as spacers to get some ideas of how to space it out, but its not working too well yet. I'll have to get back on it tommorow. Was anyone elses engine this far off?

Also another thought I had today is that the car was originally a /6 car and had a 273 in it when I got it, and I swapped the 318 in. So i'm not sure if the k member is original to the /6 or if it has been swapped.
