.030/.030 is about the smallest undersize that's reccomended, although smaller bearings are available. I'd go shopping for a crankshaft that will finish out .010/.010 if at all possible.

Were any parts cleaned up with a beadblaster? Both the rod and main bearings look like they've been run with some kind of abrasive in the oil. It's very possible to get a tiny bit of beadblast media contamination, and the parts look just like yours when it happens.
