Yes, do it! You have my full support. Swapping the crossmembers, so no front bar mods needed, is a good idea. The RB headers are indeed swappable. Daily drive the nice one with the bigger engine (it will reward you with more torque and stuff and you'll quickly fall in love with it) and race the ugly one with the built 12A. The extra weight of the 13B is a non-issue. The reduced weight of the 12A, for the race car, is also a non-issue, but I'm sure both make you feel a little better inside.
