I thought I had gotten a set of bad head gaskets but when I took the motor back apart I had 2 broken bolts that were broken inside the block. Now I have 2 broken head bolts in my motor that I still unable to take out. The bolts were only torqued to 60 foot pounds and they still snapped on me. Wouldn’t recommend to buy would find something better then these because if you buy these then you will most likely get some broken bolts --- ## 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.kr/products/430293534-12-point-head-stud-bolt-kit-compatible-with-04-19](https://www.desertcart.kr/products/430293534-12-point-head-stud-bolt-kit-compatible-with-04-19) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-15*
