Well you are right there but bearings that old for the most are going to show wear . How much you won`t know till you pull them apart then are you ready to replace.

at that point do you pull the engine buy the bottom end kit from engine builder and do the whole engine.

which just leads more decisions.

If you're oil pressure is good, they are probably fine. Have you ever had coolant in the oil (blown HG or chain rubbed through timing cover)? If so, I'd replace the bearings. If not, you're probably good.
