Thats right..... on the 3rd torque stage my new manley head bolt broke off on the #16 torque bolt sequence........ was torquing to 70lbs and SNAP.. the headbolt broke right in half...... whats the best way to get this thing out...... can you buy 1 manley head bolt? the shorter one...... Im guessing since the threads didnt strip out maybe the bolt bottom out??? dont know..... didnt have a problem with my eddy heads... yes the bolts were lubed up...... Indy EZ heads BTW...

If the threads were chased and the bolt was lubed it should come out pretty easy. You may be able to tap the bolt out with a pointed chisel untill you can grab it with your fingers or a vice grip. If not its easy out time. Id replace ALL the bolts with Arps! Whats this about you wanting 1 Bolt.  Replace them all, mike

Before you do any type of tool on it, use you finger pushing on the end of the bolt while turning, I've had alot come out easy after something went wrong. Alot of times the snap shakes them free

Wedge, I dont know the correct part number of the Arp bolts for your heads. I have it somewhere Im sure, but it maybe just as easy to call Arp. If your heads use the Same Arp bolts as the Eddy RPM,s, and I think they might. The Eddy part# for the headbolts is #8591 Witch is actually the Arp bolts. Oh, and like MrPBody said, Sometimes you can even just press your thumb or finger against the snapped off bolt and it may twist out. mike

If you cant get it out, dont drill it etc. Take a large nut ( 3/4") , center it over the broken bolt, and touch off the mig welder a few times inside the nut and weld the stud to the nut...it will come right out. Its better than taking the chance of getting drill filings in the motor.

it should come out easy- if mr p bodys trick doesnt work (try that first) there should be no tension on the bolt unless it bottomed out

I still think it bottomed out..... however without removing the head I am gonna try a hex head wrench with some superglue and let it harden and see if I can back it out that way.....
summits site:
Manley offers these superior cylinder head bolt kits for a variety of applications. They are longer than stock for use with washers, heat treated for added strength, and their 1/2 in. hex head improves wrenchability.

I've done the welder and nut thing before, it works
but I also have the welders to do it. I sure hope it
wasnt bottomed out for you

Could just be a fluke. Everything breaks. I was just talking to a guy that had two ARP studs break during install in a cummins.
I have used the manley bolts on 4 occassions now without issue. I hope you can get it out without too much trouble.
