ARP Head Studs??
They also allow you to rather easily slip the heads on and off while the engine is still in the car. The little 12 point 13 mm nut on the main studs is rather disconcerting though. Very small socket/nut to be putting that kinda torque on.
Also, mine tended to "crack" off when I undid them a couple days ago. You know how a bolt kinda makes this cracking noise/motion after its been very tight and might have corroded together with the bolt?

Thats what they look like.
Also, last but not least, one of the bolts pulled the stud out with it when I was taking it out. All efforts to get the bolt off the stud have been pretty futile. Might just ask ARP for another stud/bolt pair.
