re
 four inch of stem left

If I follow you right ..that is a LOT of bolt or stud left to grab.
I use Kroil penetrant ...
lots of it .......and sometimes that doesn't work.

you can sure grab it with a vice grips or a Stud Removal Tool..
and I use heat a lot..
oxygen-accetylne.  Have to be careful of course.

depending on access ..
I like them broken off flush, or don't mind it ..
since it's not that hard to drill a hole right down the center of the broken
off stud or bolt..
about 1/8th inch with a sharp drill bit..
i don't use cobalts much because they are brittle, and jam and break easily.

once there's a hole down the middle ...dead on center,
then I just drill it out bigger and bigger ..
until finally the remains of the stud and threads collapse...and I can just
pull that out with a forecips ...
or I can tap the hole to the original threads.

there are tricks to it for sure ..
dead on center is one ..
keeping the 'cut' going ...drill speed...
you want a medium speed and plenty of metal falling out while drilling ..too
fast, you can loose the cutting action ..it's a matter of drill sharpness,
speed, and pressure.  Get those right and it's easy. And dead in the center.
and that's pretty easy to get since as you are starting to drill the hole,
you can tilt the drill around to 'move' where the hole will really be when
it gets going well.
