Removing a destroyed head bolt -- any suggestions?
1999 D2, but that's largely irrelevant.
The flats on one of my head bolts have rounded off, so it's at full torque and I can't loosen it. Of course it's one of the bolts at the bottom of a valley, so I can't get a grinder or Dremel down there. I have the other bolts still torqued down to try and reduce the tension on it, but I'm not having any luck getting it to move.
I have drilled into the center of the bolt but I don't want to run the risk of going astray and damaging the head. I don't have any faith that an E-Z Out will be able to handle the necessary torque. Does anyone have any suggestions?

Have you try a 5/8 12 point socket?

Craftsman makes a damages bolt/nut remover. You hammer it on the bolt head. It will cut into the damaged head, and continue to dig in as you apply torque.

You need something like these. I have some from Snap-on and they work great

Worst comes to worst, get your self a nice set of cobalt drill bits. Start small and keep drilling until the bolt head comes off.

Well, I managed to get the bolt out, after much careful grinding and drilling and aiming with a narrow cold chisel.
The two sockets in the background are the ones that split when I was first trying to remove it, when the bolt was still mostly intact.
Damage to the head itself is minimal, thankfully.
