He was lucky enough that the bolt broke off in a somewhat jagged pattern so he just put it back in and fin-angled it out.

I've never had a head bolt break off, but i have broken an intake bolt. What i have had the best luck with is the Craftsman drill bits. They have a reverse drill bit on one end and the apropriate sized EZ out on the other end.

They were ARP Head Bolt's. They are replacing it for free though. I will be taking the heads off in the spring to replace the heads for some patriot performance stage 2's and I will be getting stud's next time.

TTT, I had one break too. My dad was doing it to the torque spec ARP gives, with w30 oil. It was only the third bolt. Hole was cleaned with air prior to this. Torque was verified with different torque wrench, what could be happening that they are breaking on people, aren't they a lot stronger than stock? TIA,

The other possibility is it bottom out in the block. This is a possible if you milled the heads a good amount. It's this reason that I went with a set of ARP studs rather than bolts. I was tired of the pain in the *** torque to yeild GM bolts, so I bought a set of ARP studs to avoid that problem.
I thought I had read somewhere on here that you need to use a shim or washer to ensure the proper length when using the bolts on a head that's been milled. One easy way to check is compared the GM tty bolts length vs. the ARP's length.

Yeah, an update, A shop used EDM (electro spark used to accurately corrode bolt) and they got through the bolt, and inserted an easy out type tool and the bolt still wouldn't budge. Its gotta have something caught in the threads or something. Its in there good. They are gonna try drilling it with a huge drill press.

Happened to me too.
