MAN OF STEEL
As long as you have the top slightly tighter than the 2nd you’ll be good to put them in at say 0.35 and 0.4
You just have to be careful with worn cylinders, hence having to measure top, middle and bottom of the bore.
Too big a gap may result in excessive blow by, too small and it might wear the rings excessively for lack of room for thermal expansion, and still create blow by.
