If the head is off, I would 100% recommend you turn the motor over by hand to observe valves..Also, I would individually inspect each valve while open and closed to make sure there is no build up on the valve or a bad valve seat and make sure it is sealing effectively. A little carbon on the valve can wreak havoc on compression. If a valve has any issue, the time to fix it is while the head is off.
