As Terry Burtz suggests, using an EDM machine works great. I had a broken head stud removed locally by a shop that had those machines and the stud was removed quickly and the stud hole was in perfect condition. But the block was out of the car and apart which does make it easier.

I have two on my B block that heat didn't help before they wrung off so I'm not going to bother with it to remove the remains. I'll grind them as flat as possible and locate a small hole in the center of the stud, them work the holes larger until only the threads are left. Been doing it like this for years in an industrial environment. They've been soaking in PB blaster for a couple months so hopefully they come out easily.

I did use one of the "cheap imitation" versions you can buy various places and it worked great on a couple of balky studs. Dunno how it would work on something that was seriously seized.

I use heat and vibration to break free a rusty stud but I don't spend alot of time on them.i give it one or two trys if it doesn't come it stays..the trick is to center the pilot hole and drill square to the block once you dress the broken stud flush.I use a mag drill for this, make life easy.By using a timesert I drill beyond the stud,basically tapping the grey iron for the insert...so I ultimately do get the stud out...by drill

Hello Hardtimes, the one thing that no one has mentioned is that you are now forever traumatized when comes to cylinder head nuts and torqueing them to 55 ft-lbs. Many years ago I had an engine rebuilt and I stupidly told the rebuilder that I wanted to paint the head separately from the block. Even though I had a new stud/nut set and a torque wrench, one of the studs was soft and broke off flush with the block. There is nothing worse than the experience of turning the torque wrench and watching the torque value decrease! Now I always spend a little extra and get the extra grade studs and nuts. Even so, I still have high blood pressure when I walk up to my Model A with a torque wrench in my hand! Ed

If you can find and use CCW bits there is a pretty good chance the stud will start backing out before you get to the threads.

FWIW, I've had pretty good luck using left hand drills to remove broken studs, but I've only tried it in a drill press or mill. Never tried it freehand.

I order Timeserts from https://www.threadkits.com/, have had good luck with them.

I’m not new to breaking off head studds, by any standards !
I have tried most any method could be thot up.
When a guy knows what to look for, and finds worst conditions... where studs ARE GOING to break... I figure no harm to ask if there may be a new IDEA out there.

This Goodson tool is NEW to me. I have a bud who is engineer fellow. He said ‘try this’, so I will try it !

Dont have much faith in stud removal tools/apparatus. Have broken EVERYTHING tried over decades.

Cant give up. Damn things have to come out one way or other.
Have not tried tig weld washer nut process as do not possess Tig. Guys say that that doesn’t always work.

My studs have been in this B blk forever... looks like, as they are rusted into stud .... right at block.
It may not.be pretty, but they will come out.. in little pieces if necessary.
Can you say inserts/ timeserts.. whatever.

Do not want to go caveman on this blk. But do remember how to ... if that’s what it takes.
