Chances are good that you'll find cracks in the head.

I is also as likely, that the cracks will be insignificant, and might not even be leaking. I've pulled apart a good engine for parts, didn't use coolant, had the head pressure-tested, also good, but there were two visible cracks in the usual areas. No need to pull it apart if it is asymptomatic or the symptom is minor enough to not affect reliability/driveability. Put a lower pressure cap on and water-wetter in the car.
