RS4 engine rebuild

Looking for some feedback, considering picking up an RS4 engine. Has compression between 165-190, leak down was less then 10% in all cylinders. Engine was found to have cylinder scoring. Oil is getting into one of the downpipes causing a rich code on bank 2 and a lean code on bank 1. This all came about because one side of the engine had a large amount of white smoke coming out of it. Thats about all I know, I have never heard of engine scoring to cause an issue like that, sounds more like rings? I was considering picking it up to sleeve and rebuild with OEM components. Reasons I am considering this: Yes I know JHM is working on a program, I have already been in touch and they are not currently taking any more engines on at this time. Engines are not easy to find used, I have some methods of getting a low mileage one but I do not know when that would be. Thoughts? Reasoning?
