Quality of the casting itself seems good other than that, I Just had to clearance the head for the camshaft with a dremel, BE WARY too test fit your parts & check for clearance before installation. ### ⭐⭐ 2.0 out of 5 stars Not the best *by R***D on Reviewed in the United States on October 16, 2020* Had to make modifications so the cam wouldn't hit the head. Also the valve cover to head fit isn't good at all. The vavle cover doesn't sit flat onto the head. I just hope once I have it up and running it isn't leaking from the valve cover --- ## 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.co.uk/products/114291099-replacement-performance-complete-cylinder-head-camshaft-for-1999-2000-2001](https://www.desertcart.co.uk/products/114291099-replacement-performance-complete-cylinder-head-camshaft-for-1999-2000-2001) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
