Toyota 1HZ cylinder head assembly A class 171529A

This Toyota 1HZ cylinder head assembly suits workshops and owners who need a solid replacement for worn or cracked heads in the 1HZ diesel engine. The casting sits clean, the ports line up well, and the head works smoothly once fitted with the rest of the top-end parts. It’s a practical choice for anyone rebuilding a 1HZ engine used in Land Cruiser and similar models. If your old head shows overheating marks or uneven compression, this assembly helps you get the engine back to steady running.
