Try starting the engine, you could just strike lucky and the bit will pop out, failing that I recon it's head off time.
Good luck.

PS: place a heavy but of cloth over the offending glow plug hole before you start the engine.
DO NOT START THE ENGINE.................
You will run the risk of the broken off bit getting trapped either under a valve or down the side of the piston. Try all the other stuff if you like but I would personally take the head off and do it right from the off.
Thank fook you said that, had a few like that where it stuck in the valve and it snapped the head off the valve then the head of the valve went right into the head, damaging the valve insert and even if it didnt it will damage the piston like firing bullets at it, a bit. Even had one that knocked the valve insert right out and through the piston.
In actual fact I dropped a screw as an apprentice from a rocker cover, and it went down the carb, not being able to find it I got another from the stores, not knowing it went down the carb off course, and when I fired it up it jammed a valve the bastid and bent it. A fokin v6 as well.

The reason the tip of the glow plug broke off is due to the fact that it is gummed up in the head with carbon, so very little chance it will drop into the combustion chamber.
But I do aggree, taking the head off is the best bet.
