I was adjusting my rockers on a 67 327 engine. When one of the bolts wouldn't turn either way, broke off. How do you remove the stump to make way for the new one? Are these pressed in? There is no nut at the base of it so it isn't threaded into the head. Anyone have any useful experience with this sort of procedure? I would appreciate some input since I am a bodyman more than a mechanic.
The only way to get that out is to drill it. You have to drill in the centre slightly smaller than the diameter if the stud, then get the rest of it out with a small punch.
I would suggest removing the head to do this and then pinning the studs, especially that one.
Can this be done, on the engine? How would you punch it out? Is there a hole all the way through the head? And what do you mean by pinning

1...it could be, but be very careful where the shavings go
2...you drill out 90% of the stud, there is just a thin circle left when you finish drilling.
3...No, there is not a hole all the way through, you have to be carefull not to drill too deep.
4...Pinning is putting a pin sideways through part of the casting of the head and through the stud so that it doesn't pull out
You are the machinist..................just trying to go the low buck route. That's the way I look at things.................lol
Thank you all for the input. I'm the kinda guy that checks out what the options ARE before I do something that I am not experienced with. Potential problems can be worse than the original object problem. I'll let you all know how it turns out later.

poncho, i did not respond trying to undermind what you had suggested, but in the long run for a guy with little or no experience in automotive machine shop backround i took the position that i thought was the best for him.....my response was not meant to insinuate that you did not know what you were talkin about....as what you spoke of was once one of the only ways to do the job...especially for the "backyard" mechanic...no harm intended .....charlie
No offense taken................
If you can afford it, Streets is right on the mark; have the studs converted to screw in type. The only reason the factory does not use them is cost savings.
