I think you just asked the question that has plagued mankind since the
invention of the Easy-Out.
I've done it a couple of ways...
1. Use a good punch (read real forged steel, not "import quality") and peck
away at it, chip at a time.
2. This "invention" of mine was borrowed by a fellow name Lewis or Louis,
it's my rendition of the <choose you spelling here>.."Louis-tool": used to
drill out pushrod holes. Basically you'll need to make a block of steel with
3 holes in it, the two outer holes will serve to bolt down the tool (yes,
you'll have to drill and tap two new holes on either side of your bad hole)
and the center hole is used to keep the drill bit in as a guide. Make all
holes as tight as you can to minimize the offset you'll get when drilling,
chances are you'll still need to open the original hole up and put in a
heli-coil, but you can at least get the Easy-Out, out.
