broken rocker stud removal

i have a 350 in my camaro, and noticed a miss in the motor. found a broken rocker stud. i don't know much about the heads, but if it has screw in studs can it be removed with an e-z out? if its a pressed in stud am i screwed? i cannot tell from the broken piece weather it is a screw in piece or not. has anyone ever had any experience with these?

Screw in type will have a hex at the boss side of the stud. You can remove then if you use an easy out or any other manner. It's probably best to remove the head and let a machine shop do for you. It's a inexpensive procedure.

If it's a screw in type, the you might be able to get away with using a pair of vice grips to unscrew it if there is no place to grip it with a wrench. For press in, you could use the same vice grips to pry it out, but the risk of damage to the head isnt worth it and pressing another stud in while the head is on might not be such a good idea. But up to you.

I never knew that chevy's differed from olds/buick so much. I wonder why they just did'nt use non-adjustable rockers like olds/buick so problems like this dont happen? If a rocker bolt breaks on a buick head, then all I have to do is use the vice grips to un-screw it and just replace the bolt

Oh well. Machine shop does sound like the best option, but I'm sure they would only charge a few bucks to do it for ya.

not all screw in studs have a hex on them that torques against the stud boss.that said,odds are if they aren't hi-perf castings then they are press in studs.
I'd try this little trick-put a flat washer over the end of the broken stud and weld it to the end of the weld a nut onto the washer and after it cools try to unscrew the stud.If it turns but wont come out then pull like mad as you turn and it should pull out.
this trick works great when removing broken bolts and should relieve the tension on a press in stud as well.
good luck
PS. don't weld the washer or nut to the head

Make sure once you get it fixed that you check out the push rods and that they aren't bent...
