If you are unsure of crank or rod, the only safe way is to use plastigauge, THEN buy the bearings.
I can't really answer your question, this is your choice. TBH i'd never put a stock rod back in an engine; getting the rod in / out is very time consuming, the price of some forged rods clearly is insignificant compared to the time and costs of gasket/coolant/oil/bolts/measuring needed. Throw in forged internals correctly, get peace of mind for the whole engine life.
So yes, if the rods are out, I'd have bought a set of 4 forged rods and pistons in your, or i'd have slapped another engine and transmission in there ( i am actively trying to decide wether i seriously upgrade my engine with forgies, or slap a turbo inline 5, inline 6, V6 or V8 in there)
