I've written a couple of books on the subject
. Generally a new bolt and new barrel will headspace perfectly, particularly if they come from the same vendor, if said vendor also builds rifles & uppers. At Fulton ARmory, for example, we don't want the hassle of "adjusting" AR headspace, so we make the parts to the print.
You should always check the headpace of the assembled upper anyway. Once assembled,
NEVER swap bolts.
