That's a beautiful example, Johnny...

The only thing I could have suggested is that if you had a drill handy, you drill the tops of the head bolts, blow them out with compressed air, and then thread in some self tapping screws with loc-tite on them. In about 10 minutes, you'd be able to put a socket on the self-tappers and pull the broken bolts out.

Regarding not reusing head bolts, I've done it, it's never recommended, but on any "Torque to yield" specified engine, it's never a good idea, and will almost always end like this.

Torque to yield, for those who don't know, means that you literally torque the bolts until they're ready to fail. You're actually stretching the bolt in the bore.

Lots of newer cars don't require a specific torque value anymore... they usually require something like "torque to 90 lbft in 2 steps, then turn another 1/2 turn in sequence." That means those bolts aren't suitable to use again.
