As I stated earlier, I would check headspace at approximate tdc. It may be too long already. My experience has been that as tightened, the headspace will decrease by .002/.003 when going from hand tight to index tight. The barrel/thread timing, receiver face and lock lug position and(I'm assuming used barrel)in this case, chamber will determine usability, regardless of shim or roll. bear in mind, in this case it'll take .007 to .008 just to get to hand tight tdc plus what is needed to achieve proper tightness. Also, if not far off, Bula does make long/short bolts that can help
