And yes there’s enough clearance for your exhaust manifolds! ### ⭐ Two sets failed! *by A***R on August 4, 2024* I've bought 6 sets of these for GM gen3 and gen4 LS motor rebuilds/updates and out of that I have installed 3 of the 6. Out of the 3 sets installed 2 sets have failed now. The heads and block for each build was machined by a reputable shop, verified during build, all the bolt threads were chased, ARP moly lube was used on the studs/washers/nuts, the tightening pattern and procedure was followed and GM performance MLS gaskets were used. While removing the heads for a coolant leak into the crankcase on the most recent I pulled the records and verified final torque was done at 80ftlbs after letting them sit for 15 minutes at the previous spec. So setting the same torque wrench used to install them to peak and backing each one off the highest torque reading was down to 48.6ftlbs. They are not a 180,000psi bolt as stated if they stretched enough to drop 31.4ftlbs plus of torque after just 300 miles. Needless to say the other 3 sets I have will be going in the trash now! Spend the extra money on a better bolt/stud set!! ## Frequently Bought Together - PQY 12-Point Cylinder Gasket Head Stud Bolts Nuts Kit Compatible with 04-19 Chevy LS1 LS3 5.3L 5.7L 6.0L Engines​ 234-4317 - PQY 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 - Camshaft Retainer Plate Gasket Compatible with LS Series Engines, &Bolt Kit ARP 134-1003 Gen III IV V for GM LS1 LS2 LS3 4.8 5.3L 6.0L 6.2L Vortec Corvette Cam --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/473078632-12-point-cylinder-gasket-head-stud-bolts-nuts-kit-compatible](https://www.desertcart.hk/products/473078632-12-point-cylinder-gasket-head-stud-bolts-nuts-kit-compatible) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-29*
