You could bore the # 4 and 8 moving them so you bore .030 against the front and .010 against the rear (c/l moved .015"), it depends on how much you need to bore to clean the cylinders up. I do this all the time, moving the cylinders if there is significant core shift. As long as the rest of this block is so good that is what I would do, if you have to bore to 4.080! My
