Worst possible case scenario is that you completely undo the lock and reg nut on the valve and the valve drops into the engine. Chances of this happening are small if you are aware it can happen.

Basically if the valves are to tight they can actually stay open and never fully close. A proper gap also allows for better oiling of the cam lobes.
