I assume this is a stud to mount the head, judging by the length you mention.� A cam-type extractor might work but this type repeatedly slipped off the 3/8" nub of exhaust stud I had left to work with.� Try soaking it with PB Blaster and then heating with a torch before attempting removal.� I also had a welder try three times to weld nuts to the remains of the exhaust stud and that kept breaking off little pieces until all I had left was the flush nub that had to be drilled out.

Good luck!

At least you have a piece sticking out. I hate when they break flush at the
base. Any way the easiest is to weld a nut on the end. Find someone with a
MIG welder and ask them to do you a favor. Sometimes some heat is also
needed to get the threads free.

Hi to all,
I'm still not sure what's the best way to take a broken stud out.� This one
has four inch of stem left and it's in the corner with the least space.
My question is; what are all the methods that can be used in the process,
what spray can help, etc.

Best wishes to the New Year to all,
Zoltan
