If you buy that block the very first thing you should do is to make sure that it was properly crosshatched so the cylinder walls will retain oil and provide adequate lubrication for the rings. The OEMs and ring manufacturers have developed very specific surface finish and bore geometry specifications for their engines and rings. Also consider what type of rings you are going to use Cast vs. molly rings. Just be sure that the bore finish matches the ring either way you go.
