I would still be very wary of using an easy-out... I have found the hard way that if the torque applied was sufficient to twist the bolt head off, the easy-out will also snap.
Love the "refuse to break bolts"... let me know how that's working out :D
Now everyone breaks them for me. And just for fun, I wish my problems were this easy. Somewhere I lost an entire set of 1966 383 pistons and rods. Try starting your car with that problem.
