The only real option is to pull the heads. All it takes is for a piece to drop past the precup and take out a piston. You could try to blow some air into the injector hole and hope the pieces come out the GP hole, but it's a long shot at best.

I have heard that it might be possible to take the exhaust manifold off and thread a small vacuum tube into the chamber to get any pieces that may have fallen in. Is the engine loose or is it installed in a vehicle?

If the heads are off the engine, just remove the precups.
With a small drift you can push/drive it out.

ok guys I did take a drill smaller then the glow plug tip and drilled down and cought the burr on the glow plug tip and while spinning the glow plug around i pulled up on the drill and la la the glow plug tip came out. i got all 5 done this way. but still have one that is snapped off inside the head and easy out will not take it out at all. I need to find out what thread size the glow plug is so i can buy a tap and have my dad drill and re tap the threads in the head for it.
thanks,
jimmy

Jimmy, if the heads are off, just unthread the glow plug and when it breaks off, take a punch and drive it through to the combustion chamber. As far as what the thread pitch and size is just use a thread gauge.

I feel your pain....
I snapped off the extractor on a broken g.p. in my VW.
Cyl. head needed to go to a shop with an EDM machine to remove it.
Walton Tap Extractors, Tap Extensions, Pipe & Stud Extractors and Ergonomic File Handles did mine. Nice job.
You can Google others. There's one in CA. email me if you'd like the link.
Good luck.

The closest match to the glow plug I had was a 10mm x 1.25mm tap. The tap diameter was a match but the pitch was still too course a thread. I think its safe to assume that 10mm x 1.0mm is the correct size.
