Broken head bolt, in the block, with the head on.

Providing the broken piece is still loose the cheapest and easiest way to remove it is with a good old arc welder.
Find a piece of clear vinyl hose that fits in the hole and bottom it out
Wrap one stick of whatever welding rod you have in tape leaving just the tip uncovered and connect the ground to it. Stick it down in the hole staying off to the side.
put a rod in the positive lead and stab it down to the broken piece. You want the rod to stick to the bolt not weld so when it sticks unhook the rod from the lead.

Pull the ground and hose and usually they spin out with little effort. If it breaks off start over and turn the welder up.

I reallly would have the torque wrench calibrated. Its always been a good idea to do this yearly if your using them often. Always leave them adjusted to the pounds the factory recommends. Never leave them with 30 or above setting on them. Thats a sure way to ruin them. The JB weld sounds like a good idea. Thats for the pic. I think that will unscrew easy too. Maybe a very powerful magnet will unscrew it too.

Here goes, couple days after it broke I used the top part of the bolt and was able to turn the broken piece "up" or out about 1/2 inch.
Finally today, took the head off, got a small hole drilled in the top of the broken piece.
Took a larger than needed easy out and tapped it in the small hole.
That was enough to turn it out the rest of the way.
Just want to say thanks for everyone that chimed in, it all helped, the OB rules.
Now I'm really paranoid about cleaning out the rest of the bolt holes on both sides.

Glad it's all good!

Now are you going to stud, or just replace the broken bolt?

Really glad its out and no damage was done to the block threads. Replacing ALL the bolts with new is a great idea.
