If concerned about making sure that rings seat quickly and positively, use modern thin rings. My latest B took maybe 1/2 hr on a stand. No oil burning, no blow by and no smoking. You can use all other internals as you wish/have. Thin modern rings seat quickly in a properly prepared cylinder. Of course, you have to have pistons for these rings, but if starting a rebuild anyway , may as well not have such seating worries !
