Get a Cobalt bit (not high speed steel) and drill center out and try a
easy out. It that fails, drill hole larger and retap threads. Note,
you want a Cobalt bit because not only will they cut it good (far
better than steel bits), they are also harder to break by accident.

What is it flush with? The head?
If so I have heard of folks putting a nut there and welding it in the
center of the nut onto the stub if there is even just a little showing,
then using that.
I have heard of and seen folks use a fire wrench (cutting torch) and
blow the sucker out with that. It seems to work.
I have heard left hand drill bits can work.
Things like 'easy outs' are a failure 99% of the time I have seen, used
or heard of their use.
'I' can drill out 99% of the ones I go after without damaging threads
much if any. Many years of Practice from living in the rust belt helps
there. :-(
I use a small bit and drill a pilot hole offset from the center of the
bolt. I then use a bit that will fit from this pilot 'just' to the edge
of the threads and drill. This leaves a crescent moon shape of the bolt
that can be backed out with a screwdriver or hammer and center punch.
Good Luck!

Re: busted header bolt
All of what Mike said but especially: do NOT try an easy out. The bolt
is rusted in, you will snap the easyout and then you have no hope.
