Re using cast iron rings?

I it is not an old timers trick. So u have heard the saying do it right or don’t do it at all. It’s a lot of work to go thru having to do it over again. I only ever have time to do it right and not over again. So far that has worked for me for about 50 years. I think ur gonna have an oil sucking pig that can’t get out of its own way. So are u probably use the old bearings and oil pump along with the timing chain and gaskets. Kim
I'd go with new rings regardless. I've never reused bearings either or the oil pump I guess that you can.
