checking rod and main bearings

[fftoddster]

I have read several threads where it has been said that many times the floating rod bearings are reusable.

Before I pull engine apart can I/should I plastigage the bearings to check for wear (besides visual inspection)? I'm sure that best way would be to mic everything but I do not have mics.

New to the floating bearings. Can they be checked with plastigage? would it be done on both inside and outside of bearing at same time?

I'm trying to find more info on the floating bearings (have some books ordered but don't know how in depth they will get) All I have heard is the are not easy to set up properly...
