You have to have all cylinders freed up before you start it. The idea is to have any lip removed and clean and the engine rotating freely by hand; before you start it up.
Rotate the engine by hand, if the rings stick on something, figure out which cylinder it is and make it smooth.
A brass wire brush and petroleum jelly works good. You can soak the cylinders in oil. Don't scrape with anything harder than the cylinder walls and if you can't get it smooth, I think Honing is your next step.
Pictures would be helpful showing how much of a lip is present.
Also, how long has the head been off?
