Depending how much stud you have sticking out the block. You could weld a nut on them if you don't have enough for an extractor. Did you get my message?

A bit of, well a lot of, heat( Oxyacetylene, OA) helps if you have enough room and if wont damage anything. It will help to free them off. All those years they have been in there will just make them want to stay, Son of a bitch is dug-in like an Alabama tick. Plus use what staggard said above.

Can I also add, if you try any kind of "easy out" type of extractor, use the fluted type that you drill a pilot hole then tap it in. They come in tapered and parallel designs and are far better than the left handed spiral type in my experience that Cam out. Also don't go gun ho, if they are really tight, stop and rethink. The last thing you need is a broken, hardened, tool to have to remove as well. You could end up having to take the block to and engineering shop to have it spark eroded. Richard beat me to it. Note to self, learn to type faster  |

Dave you should have given me a shout. I am sure this would have gotten the studs out Made from an e type jag axle bolt and a cut down air chisel . Might take 5 to 10 mins per stud also leave the but on so to protect the head.  __   |

I have always found that, if possible, drilling out the old broken bolt works well enough. Start with a small drill, get it perfectly central, then go up in size until you can pick the old threads out with a sharp tool.

Put a nut over the remains of the stud fill it with weld then ease but back and forth a bit at a time I had to resend but back 3 times but the best did loosen the stud once it was moving it came out very easily

Theres always enough even if it's broken flush. As seaking said you weld in the centre of the nut. The heat will help it release as bulstartz said.

loads of different methods on youtube👍 I have had success drilling down inside the broken bolt and giving it some serious heat, then welding a nut over the top but before trying to shift it give the block some heat.
Neither method alas worked on mine, was nervous about drilling the stud out for fear of damaging the thread so too the machine shop it went
