Which manifolds? 2014 5.7

I'm in the process of a 6.1 swap, 68 Barracuda. I just picked up a full pull out 2010 Challenger, Engine, Trans (6 Speed) wiring, computer, dash.
Trying to get all issues worked out. not sure what headers will work with right side starter, and stock suspension (at this time) I do have a QA1 K member. Not sure if I'm going to use it. Torsion bars seem to be an issue with right side starter trying to find headers.
I have a machine shop at my house so some of the fabing I can do, the wiring and computer is a different matter.
Keep me posted on your build. Need all the input I can get.
Thanks
