Well I see what you are saying - that would be pretty incompetent. You wouldn't have to remove the head to check though:-
Set the engine with the markings to TDC for number one cylinder. Remove the front group of rocker arms and remove the valve nuts and valve spring on one of the valves on #1 cylinder. Carefully lower the valve onto the top of the piston crown.
If the piston is indeed at TDC the valve will drop by a few millimeters say 6mm.
If the valve stem starts to disappear - quickly pull it back up before it drops into the cylinder... otherwise will need to remove the head to retrieve the valve.
FYI - this is part of the procedure in the FSM for setting up the position of the tachometer sensor on the front of the engine.
