That is scary. Are they ebay ARP studs? Chinese knock offs?

Cool build 
I wouldn't worry about the stud. In the picture the fine threads look dry? Did you use any of the ultra-torque assembly lube the threads and underhead of the nut?
Fasteners will break every now and again. Hell, planes still come out of the sky as well. It happens. ARP can't fully 100% inspect every single fastener moving through their plant, or the price on them would be insane. Still doesn't mean they aren't valued and trusted for their quality of products everywhere in and out of motorsports. I've tested their fasteners in a lab setting on an MTS and failed their custom aged 625+ studs (though it took an absolutely ridiculous amount of load
), and they all failed within 0.6% of each other.
If you want to do your own inspection, take a new set of studs and measure full end to end length with a good gage. Torque to full spec, remove, and remeasure. If there is any elongation, there is a problem with that fastener and should be replaced. Can't do this with a used or already torqued fastener, unless it happened to be measured before first use.

ARP didn't have much to say... just that it had to be installed wrong and was user error... which wasn't the case. Given that info, it must have just been a fluke break and the others should be fine I would imagine.

picked the motor up from the builder on sunday... it's back home on the stand, should drop it in soon.
It seems like I'm on a streak for breaking parts that shouldn't break though....
First that melling oil pump spring, then when the heads were going on, one of the ARP studs snapped. Thankfully the break was so jagged it just unscrewed with some downward pressure.
Anyone ever broken one of these before?

Just got my stock size arp balancer bolt for the ati balancer, didn't realize innovators west used a different size. Motor will be in this weekend, then some fuel system updates with an in tank walbro 450 and flex fuel, then centerforce clutch and driveline go back in... probably 2-3 weeks depending on heat and work travel schedule.

More parts... now that I have my flywheel I can lock it and torque the balancer bolt, then drop it in this weekend
Racetronix goodies including a walbro '450' in tank pump:
Centerforce DYAD clutch with dfx discs:
Picked up the fittings I needed for the tight firewall fitment on c6 vettes:
Local guy helped weld my Tial 50mm flange to the new intercooler:

Holy crap that is an expensive intercooler. My custom one that will be a bit nicer will be ~1/2 that or less.

Obviously its not hard to source a cheap intercooler/core these days, so it goes to stand why our systems do cost a little bit more then some. LOTS of companies,.....wait, pretty much everyone has been or has swapped to the massively cheaper Chinese cores (or other countries) to save a good deal of money on their kits, or custom intercoolers.
However, when we say "Made in the USA" we really mean it. One of our biggest costs is american made intercooler cores. We take pride in our "Imagined, Designed, and Built in the USA" concept, and we are sticking to it.
Not saying there is anything wrong with other cores, just being honest in the fact that is costs us a good deal more, on LOTS of aspects of our systems, to make sure that our $$$ stays here in the states.
