No lip, Lip is a sign of bore wear. Rebore is the best way to go if its getting done properly

There is a chance it may smoke, If there is a lip at the top then the will be quite alot more wear further down the bore where there is more thrust. From past experience re ringing an engine doesnt work if there is a lip at the top, There were ok for about 500 miles or so then they started to smoke and it just got worse.
