Default Budget/eBay head studs

KMJ is out of the 04+ head studs... what other budget studs have you used with good luck? Alper Motorsports doesn't have them listed on their eBay site anymore either. I need to order today.

Without getting into a debate over quality, forging in the US is hella expensive as opposed to China. US steel costs more than Chinese steel, is purer than Chinese steel. US labor costs more than Chinese labor, but also helps revitalize OUR economy. To top it off, our government doesn't really tax imported goods, so all in all with no other considerations, the part made here costs more to make. So, it is partly the government's fault...

I'd rather pay salaries than welfare.

I agree, it is outrageous. I didn't mean to sound like someone ranting.

I wonder what the preload on the stud would be at 55 lbs. I was cautious about torquing to 80 lbs on an Al block, so I stopped short.

I torqued my arp studs to 80ft lbs in the aluminum block, no problems. Now a head bolt yea that would sketch me out some.

You get what you pay for, as they say.

I've had the opportunity over the past few years to tour the ARP facility. Without a doubt, the one thing they are super picky on is quality.

Around the production areas, you'll find quite a number of these inspection machines. These are to ensure whatever process they are applying, is being done properly. Depending on the station, as many as 1 in every 10 bolts is checked for consistency. For the pro teams, F1, etc, every part is checked at each step in the process. We're talking at least 30 different stages, depending on the bolt.

Another thing that is apparent is how clean the place is. Making bolts and nuts is a messy job. Oil, cut material, blast media, chemicals....with all this going on, they keep the work areas completely spotless. Again with the quality thing.

The QC area and the stress test area are pretty amazing. Watching them destroy hardware is pretty impressive when you know the material it was made from and what its officially rated at. Something else I've learned over these visits is the extreme importance of Ultra Torque. Consistent load every single time. Rather amazing stuff.

Couple of videos of the heat treating process included here too...

Bottom line for me is, after seeing every step of the process, and knowing all the REALLY cheap junk on the market and what their tests have revealed, I wouldn't use that crap for carb studs, much less something important! Its ARP or nothing for me. if its important enough to buy, its important to fasten it with the right hardware.

5.3 making just over 800 at the crank at 20psi, (calculated by mph) cranked down to 70lbs.
$600 engine gets $70 studs, $6k gets $300 studs.

I just bought some from Aplper motorsports. After reading all the broke stud storys I borrowed a calibrated torque wrench from work and used moly lube. I torqued them down to 30,50, and then 70. No problems with mine. I only paid 350 for my 5.3 so I don't mind rolling the dice on head studs. We will see how they hold up to boost in a few months.

Theres a reason why quality costs more and there is a difference between the two. I'll take Ruths Chris please. I'll cut costs on my cable tv package, not on my LS!

To each their own. Fact is BOTH the ARP and these budget studs have proven themselves.

https://ls1tech.com/forums/generatio...sold-ebay.html

Plenty of guys in the above thread running the "get what you pay for" studs that are deep into the 10's. Including one car making 928/926 to the wheels. How long will they last? Guess we'll see. Point is that this argument has been beaten to death. 10 pages in the thread above discussing the very same thing. Like I said... to each their own. Personally, I'm with the others... my cheap *** junk yard motor will get cheap *** studs... especially if the cheap *** studs have proven themselves in countless other builds. I think most of the guys that purchase them are in the same train of thought as me... "I realize they might be risky to use, but it's my choice. If it blows up because of a stud, well that's my own fault. If it runs 10's and does it for a full season without issue, you bet your *** I'll use them again."

Junkyard builds for the win!

Big difference between flavor of a steak and holding down a head. Steak flavor has a bunch of variables (Texture, temperature, aging, cooking, seasoning, etc).

Head Studs... do they hold the head down adequately?
. . . Yes / No (Check one)
ARP . Yes
ProCompYes


Side note... I wonder if Ruth's Chris gets their steaks from Wal-Mart... ???

From my perspective, if you're fretting over $210 this isn't the right hobby for you. If I snapped off a chinese stud in my block torquing it down I'd be regretting not going with ARP.

Key word... Hobby... We all have a budget to work with, in my case... an extra $210 can be better spent elsewhere.

I'd be madder if I snapped off an ARP stud by torquing it down. LOL.

Anyone have a chinese stud snap off while torquing it down? Just curious as to the failure rate.

I went 80lbs on my China studs w/o issue. I'm thinking of adding another 5-10lbs after I get some time on the engine and everything settles in....
