This Colony cylinder head nut kit is specifically engineered for 1942 to 1950 45" Side Valve models equipped with cast iron heads. When you are torquing down the heads on a vintage Flathead, you need hardware that can handle the heat and pressure while providing a consistent clamp load. These nuts are finished in a durable zinc plating, offering a clean, period-correct appearance and protection against rust. Sold as a kit, this hardware ensures you have a complete set of fresh fasteners for your top-end rebuild. Colony’s commitment to quality makes this an essential kit for any 45" enthusiast looking to keep their WLA or Servi-Car running strong and leak-free.
