Pro-Comp Head Studs sold on Ebay
That's the website of the company in question, Pro-Comp. Looks like they have a rather large 75,000 square feet facility in California and claim to utilize some fairly extensive, rigorous quality control on their products. Doesn't say where any of their products are MADE per se, but my guess would be here in America. It seems their products are at least high enough quality to have won awards at SEMA for 3 consecutive years.
Have known people who have used these studs in several high power, boosted combinations with absolutely no problems whatsoever, so I suppose that's another +1 for the "Approved" team.
Bumping this because I wonder if there's anybody else who has an experience or two to share as well who may not have seen this thread.

Its like Nike. Your paying for a name, not the shoes.
Besides if we keep this thread up ARP head studs just might get a lot cheaper here in the near future. How's that sound? eBay might bring ARP bolts and studs prices to where us shad tree mechanics can actually afford them. Lol

You have problems in everything that is mass produced... you just got a bad set that was made on a Friday around Christmas!!! would be nice for ARP to lower the price but they wont to many people buy product at that cost.
I read this thread as well and thought the same thing cause 140 in lbs is only 11 ft lbs... I Torqued the 7/16 to 85ft lbs and didn't have a problem.
ARP is GREAT ****, no doubt, but I want studs, and 250+ is a tough pill to swallow. But as many say, buy once, cry once....
