Josh,
Why don't you send them your stock injectors and have them put the size nozzle you want, Stage 1 thru 5, then their Injector specialist will clean, pop-test, and balance the injectors all for a little more $. What you end up with is basically a full set that is matched and you won't have to search out a shop to do that. But you can save some $ if you have a friend with the proper equipment to pop-test and balance the injectors. The tip swap is pretty straight forward. I can send you instructions, I've got them somewhere on this pc.
Take care,
Casey
