Re: starter bolt sheared, EZ out sheared...
Just a couple of comments; The theory of heating the bolt to remove the temper from the easy-out is good, but in practice, the block will draw the heat of a torch away, making it risky.
I also have used the washer/nut/mig weld trick, it works 99% of the time. Use a washer the same size as the bolt, use a nut 1 size larger. The washer limits the weld arcing to the block. I countersink the nut first, to make more access. The weld heat expands the bolt, crushing the rust, and also breaks down any loc-tite that may have been in there. As it cools, it shrinks, can usually unscrew it with fingers.
Don't throw water on a hot part, it stops the shrinking.
Whether it can be done now with the bolt recessed depends on how deep is the recess?
