12-Point Cylinder Gasket Head Stud Bolts Nuts Kit Compatible with 97-03 Chevy LS1 LQ9 LS6 4.8L 5.3L 5.7L 6.0L Engines

Working good on my lq4.

Used these on my ls3 build. I actually torqued them down then had to remove the heads a second time because i installed a cam and wanted to change my lifters. So i actually torqued them down twice and they held. Stock build so im running 75 ft/lbs with no issues so far. Used the specs from ARP website but did not go to 100 ft lbs.

So far so good! Just intsalled and need to build heads, i see reviews saying they got shorted a few bolts or some were wrong, my pack had a extra 2👌🏽

I def like the studs and the quality... But i recieved 10 of the short M10 BOLTS AND 4 OF THE M8 bolts... So they got them backwards... Then i wanted a exvhange ... But only would refund my money.... So instead of waiting i just used em... But as far as the service and wrong bolts... CRAP!! BUT I WILL HAVE TO SAY I LIKE THEM AS FAR AS QUALITY AND PRICE... I WISH I WOULDVE GOT THEM ALL....???

Its been holding up great so far. hit 20lbs of boost (not intended, wastegate got stuck.) point is they held up. I seen that people followed ARP's installation process, I followed the instructions given in the order. so far they hold up! best bang for buck, I recommend these over the OEM bolts any day!

I would not say ARP equivalent by any means but for a budget build send em. Followed ARPS torque specs 25, 50 than 85 for mains and 28 for the smalls nothing broke went smooth. Came with 1 extra long and 1 extra medium. No extra nuts though. 1 nut was flawed a crack was very visible from the bottom 2 Threads down all the way through. Luckily I had an extra from a previous set. All else though they’re solid for the money but like others have said I wouldn’t trust em with much more than 85lbs. Great for built N/A LS. Idk about boost with these just cause the price. That’s your risk though 🤷‍♂️

Bought these for my 408 stroker build because i needed head studs by the next day and nobody had them locally. I was and still am a bit skeptical but they have been holding up fine to 15 PSI of boost with 9.5-1 CR. I will most likely order a set of Xotic or ARP to have on hand when these go bad but they seem to just fine. Update: it has been about a year and half running these studs, had the motor apart a few times and reused them each time. They're holding up really well. I've ran 18psi of boost on my 408 LS with 9.8-1 compression.... no issues whatsoever. Highly recommend these if you need a inexpensive option delivered fast

i bought these knowing they're cheap. wasn't expecting much though i wanted studs instead of bolts. this was a cheap alternative to ARP. i have these on an LS1 turbo build running 16LBS of boost and holding up just fine. used the ARP torque chart. they worked well enough i bought a couple more sets and used on some high compression builds (11:1) and they're running fine . i'll buy more soon. this set is the older style up to 03 year model.

Fit my 2001 gmc sierra 1500 with the 4.8l vortec. Good option for a stock replacement. Does not come with torque gease. I followed arp's torquing instructions

Used ARP 30,60,70( tried 80 for final pass and one broke) Here’s what needed for extraction

Was shorted bolts. Checked too late can't return them.

Studs installed good, but washers were to small for the larger bolts. Now I have a ton of drilling to do to finish this job. Other than that they seem to be exactly as I'd expected. Quality seems good so far other than the washer issue.

They seem to be as good as arp head studs fraction of the price
