DESCRIPTION
The cylinder head, with part number 3406739RX, is a crucial component of an internal combustion engine. It sits on top of the engine block and seals the combustion chamber. The cylinder head contains intake and exhaust ports, as well as the spark plug holes. Inside, it houses the valves that control air flow into and out of the engine cylinders. The cylinder head must be carefully machined to ensure a proper seal with the engine block and to provide sufficient clearance for valve movement. It is typically made of cast aluminum alloy or iron, depending on the application. The quality of a cylinder head can significantly impact an engine's performance and longevity, making it an important consideration when choosing parts for your truck's powertrain system.
