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
