there is always the build your own stud kit option. I don't know what the lengths are but 8.8 125 Ksi Metric studs.

You must have poor reading comprehension skills. Never did I defend china copies or claim their manufacturing process (or product) was anything near ARP's. Never did I claim ARP did not have a superior product. My gripe was the price difference between two very similar ARP stud kits. And that we are paying 10X+ the cost for a fastener that’s 20% stronger than standard grade 8 hardware.
The company in question (or any company) Can purchase 8740 steel stock and machine hardware from it. The process to do this is not some well kept R&D secret. With the proper equipment, any well equipped hardware machining company can make a stud from 8740. While the machine work may be poor, and the alloy used sub-par, ARP does not have a patent on the process. Again, I’m not claiming china doesn't steal designs and make all kinds poor copies. But in this case you’re wrong in thinking anyone stole anything from ARP.

I'm not going to go back and read all the pages in this thread but I will share my one and only experience with the eBay head studs. CRAP!!!!!! Not worth the $60 you pay for them. They are week, almost none of the Allen head holes in the top of the studs are machined correctly and some didn't even have the holes at all. We used them once on my dad's all motor LS powered mini pulling tractor and broke one while torquing them down at only 60 ft lbs. The old saying still stand true, you get what you pay for!

As I said in here before. I've had both eBay and arp studs. And unfortunately the only one that broke was an arp it's obviously a fluke because this isn't something that happens often but I did go with arp again this time around and just hoping for the best. But the stud broke at 62ft lbs on my last pass was really surprised to be honest. **** happens.....

And the lawsuits against Procomp or Speedmaster or whatever they are calling themselves this week? The ones for stealing ARP's trademarks, patent designs? Or the lawsuit by MSDs parent company for the same? Sure they have stolen. Its what those Chinese companies do. That's how they sell so cheap. Do none of the work and research, produce the product.

Fact is some people are going very fast on these studs. I've seen 5.0x 1/8th miles on a basically stock 5.3 at 32psi through a t88 on these "china studs". They were torqued to 75ftlbs. The setup has made many many runs at this power level without any issues.

To me a big dollar engine gets nice ARP hardware. A cheap JY setup gets cheap hardware. I see no reason for the average joe building a 500-600whp setup to blow $360+ on an ARP stud kit. The set I just installed on my motor I torqued to 70ftlbs. And I was sweating bullets at every torque wrench "click" over 50ftlbs.

Ordered studs from alper maybe a month and a half ago and decided to check them out last night.
All the nuts fit in a socket fine and are machined correctly. Also all the allen head portions on the end of the main studs were machined correctly.
Guess we will see what happens when I install them.

But I'm guessing its just a block. Not proprietary engineering here either.

Also, how far do these small studs tighten into the block? This is my first go at putting studs in an LS. The larger studs all went in fine, torqued to 75 ft-lb with no issues. The couple of small ones that I did manage to get in by hand, I ran them down until they stopped and now only about the 75% of the threads in the nut are actually holding onto the stud, since it went down so far into the block.

I just ran into this problem. I cannot get the studs to tighten into the block. I think the threads are dirty, so I'll have to find a way to clean them.

Sounds like you might have to use the orig bolts for the little ones. I didn't have any issues on my L33, but either your block is drilled deeper or your studs are slightly shorter.
