While disassembling my 91 5.8, I had the exact same problem accept the stud I broke was on the other side. I ultimately discovered the stud "shank" was seized in the timing cover and not the threads in the block!
Find a long 1/16" or smaller (I used a #50) drill bit and drill around the stud where it goes through the timing cover - you can take out a little metal and still be OK! Soak with Kriol or PB Blaster and continue to work with a small pipe wrench. - try to work in both clockwise and counter clockwise direction. Mine broke with only about 1/2" sticking out of the timing cover; I was not able to free it and ended up removing the timing cover. Perhaps you will have better luck then I did.
The addition of heat with a propane torch might also help - applied to the timing cover but use caution because all these penetrating oils are flammable!

Well I broke the first stud after deciding to weld nuts on them a d had to take the timing cover off. I got the other stud out no problem. After I got the cover off I unscrewed the stud I broke twice with my fingers. Here's some pics also I broke the cover, one piece oil pan gasket, and found this thermostat in my intake.

Well Superduty - I can empathize with your position - I saw your pictures and remember looking at nearly the same thing..... Hopefully this isn't your daily driver! Mine was a project for my daughter and I had a few months to tidy everything up. I ended up deciding to drop the oil pan - replaced the timing chain and oil pump while I was in there.
The one piece pan gasket was nice. In the end everything from rock auto only added about $100.00 to the project but it did add a couple more weekends.... Attached is a front pic of my engine after I got about 90% of it back together....
I noticed you actually broke the cover getting it off - I broke my water pump getting it off but was able to save the cover.

On a positive note - having to buy a new timing cover will save you a few hours of cleaning. By the time I got mine off I had also done some minor damage to the gasket faces so after cleaning and bead blasting I had to fill a few spots with JB Weld then sand smooth - after that I etched and alodined (Chemical anti-corrosion treatment for aluminum we use in aviation) it, then painted Ford Blue - I never liked the late model Ford Gray - The old Blue looks much better to me. In all I probably had 5 hours over 3 days in the timing cover. :-)
FWIW - I looked on Rock Auto and for just over $60.00 they have Dorman replacement timing covers, I'm sure they are not USA Made but probably OK.
Prior to assembling everything I used thread cleaner and ran all the holes in the block then blew out with brake cleaner. I replaced all the studs with New: Dorman WP Stud Kit and any place I didn't need the studs I replaced with new grade 5 bolts - wiped all the shanks with LPS3 and coated all the threads with RTV prior to installing!
BTW - first time I have seen a thermostat come out in pieces.
Was it that way or was it corroded in so bad you had to do that to get it out?
Good Luck!

That's the way it came out. And no it's a dd/mud toy. If it tears up I got other rides. I'm prolly going to change the oil pan gasket again. Water pump. Timing cover. I don't see the need for a new chain it has a double roller in it thats in good shape. Since I've had it I've did an alternator Ac compressor and now this on the engine. Its been kickin my butt today.

Use apipe wrench or better yet pick up a stud removal tool and while you are applying pressure to the tool or wrench smack the end of the stud with a hamer and dont forget anti sieze when you install.
