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.
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.

The threads on these cheap studs might need some cleaning with a small file. I had to clean up a few.
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.

For anyone on the fence about using these Ebay studs, Thompson Motorsports now makes their own studs with specs similar to the ARP studs. Just ordered a set and gonna give them a try. They are priced fairly well too.

Has alper or procomp fixed the stud machining issues? I'm debating these or maybe the newer ones from Thompson Motorsports. More expensive than the Pro Comp's but a bit cheaper than ARP.

I don't think they have them up on their website yet. Here is a link to their Facebook post about them:

Just installed my alper head studs. No issues really besides 2 of the big studs were a little tight on the allen head. Just used a metric instead of standard or vise versa.....don't remember exactly but it fit like a glove and all the studs survived torquing to 75ft/bs with arp lube.
I ordered mine a few months back when everyone seemed to have issues.
They emailed me at first and said their first batch turned out with bad threads so had to wait an extra week for a fresh batch.

Still sorting out issues with my setup. Still Slow, but I did run 25lbs on the china studs and pushed no water... 10:1 5.3 LS9 head gaskets. Done a few compression tests before and after trying to sort out other issues and all cyls appear to be sealing great for now.

Hey guys what about the pro comp main studs ? Has anyone on here used them? I just picked up a set of procomp main studs and head studs and was woundering what I should torque them both to.

I have used the ebay studs for several builds never had a problem,they look just like the ARP..which are very nice and very expensive. I have used ARP bolts for years never had an issue,yes they are more money,reason I tried the ebay studs $69 verses $500 for a ls.motor.made several 148 mph passes with ebay studs..! anything can fail!!
my money goes further on a budget..luck ,trial and error..
