Most people who have changed them out will tell you they wait until they change barrels. They are nice to have, they do help, but it is not worth the hassle just to change the lug. Also, to answer your question, if you do go to an improved lug, you may be able to get the stamped wording to return to the original orientation, assuming it is installed on the same action. If it doesn't return to the same orientation, I would suspect you have not returned it to the same headspace specs as it was originally set.
