On the measurement--did you torque the rod caps first? Are you measuring top to bottom and not near the split line? Have you double-checked with Plastigage? People rag (unfairly) on Plastigage, but it has a lot going for it.

You can get bearings in .001 oversize for extra clearance. Or undersize if needed.

Search the site I linked. They offer both over and under size. .001 should get you there. I dont really think in metric terms.
