If you are keeping the slant, I would keep the K and upgrade brakes, inspect bushings, and get a 1 1/8 or 1 1/4 front sway bar. Run it. then I would get a LSD and....run it. So for a second you might be running mis matched wheels if you go to a BBP up front before swapping in diff. See where you are at in your enjoyment level, and do the torsion bars if its not stiff enough up front. Then if you feel like the slant isnt enough power you would have to make the decision of going to an 8 or power adding. these are the steps I would do to keep a car running while working on it. all can be done in an afternoon or two. You could run it with the 6 for awhile after these upgrades but keep in mind your goals. If you want BBP or if you want an 8 as when buying front discs or when swapping diff, you want to spend your money wisely. IMHO you do not need the aftermarket front suspension but it depends on your goals. Aftermarket suspension will give you easier fitment of headers on an 8 but TTI makes headers that fit pretty good, but you will spend money there (700-1K with coating).
The big decision is.....keeping the 6 or going to an 8? I like my 6 in the Duster, but I do feel its underpowered. Its nice though and with just the addition of a big front sway bar I can come into a corner pretty hot and have a lot of fun. Maybe get a sway first? its a big handling upgrade that can be used no matter what you decide. admittedly I went 1 1/4.
