International Navistar DT466E New Cylinder Head (1823914C1) – Fully Loaded

This new DT466E cylinder head for International/Navistar engines is built with a focus on casting durability and long-term reliability in demanding diesel applications. The high-strength casting incorporates enhanced material composition to reduce the risk of cracking between valves and improve resistance to thermal fatigue under repeated heat cycles.

Reinforced internal structures and optimized coolant flow design help manage heat more effectively, maintaining structural integrity under load and extending service life in high-duty environments.

Each unit comes fully loaded with new internal components, including valves, springs, and valvetrain hardware, selected for durability and consistent operation. These components are designed to withstand high temperatures and pressures while maintaining proper function over extended intervals.

Precision-machined surfaces ensure proper sealing and fitment, supporting dependable engine performance and reducing the likelihood of premature wear or failure.

Designed for durability at the casting level and reliability at the component level, this DT466E cylinder head provides a dependable solution for maintaining engine integrity in medium- and heavy-duty applications.

Key Features:

• New high-strength casting engineered to resist cracking and heat stress
• Reinforced internal structure for improved durability under load
• Fully loaded with durable internal components (valves, springs, hardware)
• Precision-machined for proper sealing and fitment
• Built for long service life in heavy-duty diesel applications

What is this Stage 2 all about?

This stage 2 cylinder head is an upgrade from the standard cylinder head. The difference is that the exhaust valves in this cylinder head have all been upgraded to inconel valves. This major performance improvement increases the capacity of the valves to endure higher temperatures as well as heightened pressure.

There is a common fracture issue with standard valves when they are running at heightened horse-power, this superior quality inconel material prevents these types of fractures and ensures that your exhaust valves can stand the heat! If you are looking to get more out of your engine and ensure that your head doesn't fall prey to corrosion, pitting, and cracking; this is the head for you!
