Broken head bolt removal

Broke 2 head bolts removing the head. One broke 1/4" above deck and one 1/8" below.

Got them nice and hot with a GOOD propane torch (watch out - some will hardly light your alternative cigarette), gave them a few love taps with a BFH and turned out the protruding one with a small pipe wrench (better than vise grips - read it on Hybrid Z)

The below flush one presented a bit of a problem. Drilled it out with a smallish bit - size inconsequential. Used lots of rapid tap and pb blaster. Got lucky when I went to drill with a larger bit and the bolt moved a little. I don't have reverse drill bits and easy outs really, really suck. So I takes a torx socket, 15 or 20, just big enough to not slide easily into the hole I drilled through the remains of the head bolt. A few GENTLE taps put it in far enough that I could remove the bolt as if it was meant to be.

Just like a drill bit or easy out you don't want to break the torx off in the hole. No fun.
