Does anyone know if ARP makes a stud kit for the stock block with stock heads? If so what is the part number. I am having no luck and broke two head bolts before I even hit 80 ft/lbs.
Thanks

ARP 260-4702
long link that I should've converted to bbcode 
Kinda spendy, but nice. If you want them fast, like five days or less, you need to have them drop-shipped for and extra $20.
Mod edit: Sorry, couldn't resist

Does it matter that it says for phase 2 99+ EJ series engines?

The threads are correct and they are the right length. After ripping the threads out of my block with the short studs, I used these jsut fine on the next block. 26+ psi.

Sweet, I was just worried because it says it was for phase 2 and I'm sure the stock is phase 1. Snapping 8 dollar bolts is getting frustrating, especially having to drill out the broken piece out of the block.

You are using the factory bolts and torquing them 80 ft-lbs? Take a look at the torque sequence and you'll find that it isn't close to that. And it is a goofy sequence due to the torque-to-yield nature of the bolts.

I don't know how many times doug (douglas vincent here, reddevil on nasioc) has done this, but I don't recall him having a headgasket failure.
Also, the person later in the thread saying that you need to cycle ARP studs three times doesn't know what he is talking about. You are not work-hardening the material of the studs, so there is no point to it. Also, since the threads of the studs are rolled vs. cut, they are much much harder than the aluminum they are seated in.
