Does not come with torque gease. I followed arp's torquing instructions ### ⭐⭐⭐⭐ Review *by S***N on 24 January 2026* The torque test channel on YouTube tested these and they scored very high for torque before fatigue especially with cost. I was able to torque my 6.0l aluminum heads HOWEVER, one stud had thread damage from factory and I had to run a die down the threads to cut the threads from factory to be usable. I didn't bother messaging the vendor however but be aware that these are cheaper than ARP by alot and have their own quirks because of that. ## Frequently Bought Together - 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 - Brian Tooley BTR Delphi LS7 Lifters + Trays for Gen 3 Gen 4 LS + Gen 5 LT Engines X12499225-16 --- ## 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.com.kw/products/525180171-12-point-cylinder-gasket-head-stud-bolts-nuts-kit-compatible](https://www.desertcart.com.kw/products/525180171-12-point-cylinder-gasket-head-stud-bolts-nuts-kit-compatible) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
