do you think i could still make this thing a daily driver without a total tear down?

You are taking a chance if you don't. Tear it down and clean it out right. Quick refresh if possible...

You can get a "refresh" kit in A or B with new main and rod bearings, rings, and a complete gasket kit for $200.
