It has 2 different thread pitches on the stud. I just thread 2 nuts on it tightened together and then use an open end wrench to back out the 1st nut threaded on as it will be jammed to the 2nd one. This will unscrew the studs.

I noticed the ARP ones allow you to tighten them with an allen wrench. I guess I'll tighten them with the 2 nuts tightened together method.
Studs are suppose to be 'hand tight', over tightening them will cause induced stress on the threads before you add the clamp load from tightening the nuts... they should be snug, not tight, slight difference
Good luck

The allen head is really there to make sure they are fully seated, not to be 'tightened'

ARP put the allen head there because newbies were putting ARP head studs into dirty threads as tight as a weakling could thread them in by hand... Unfortunately the dirt in the threads was only causing the studs to go in 3-4 threads deep, thus when torqing down the nut, it was striping out the first few threads.. Then these same newbs would go on the internet and trash ARP for "striping out my head/block"
by using the allen key you put enough leverage on to get the stud all the way down so it's seated.
I personally always chase the threads of a critical stud/bolt hole with a thread cleaning die before installing the stud/bolt.
Agreed.

Finished! I thread chased them so it when in pretty easy. I had to use a nut on them to get them to fully thread in, but I did it very lightly. Now for my hotside studs on my turbo. I have one that is 1/2 way out. It won't budge anymore! 
I've torched the metal near the stud, I've PB Blasted the hell out of it for 2 days. I'm almost ready to take it to a machine shop. Any ideas? Someone on another thread said ATF mixed with acetone.
