Pic of the stud...

 

How the **** did you get that out with the head on? Magic?

 

Shouldn't be too, too hard to extract a broken stud. They only go in "finger tight" so they are not all torqued up like a bolt would be.

 

Haha it took some time. Long flat head screwdriver at first and then I'm sittin there thinking... Oh yeah, the broken end of the studs are gonna fit together like a glove. Shoved the broken end back in and put some pressure on it. Turned it out and grabbed it with an extendable magnet. Called arp today they're sending me 2 studs, 2 washers, 2 nuts and another packet of lube. Figured I'd ask for an extra stud this time just in case.

 

UPDATE: Head studs in and complete. This can be locked
