What makes these heads suitable for high-performance diesel applications?

These heads are cast from A356 aluminum and undergo heat and pressure treatment, including a Hot Isostatic Press (HIP) process, for increased strength and durability. They feature a thick 15.5mm deck to handle higher cylinder pressures and are heat-treated to T7 hardness for extreme diesel operating environments.

Can I use my existing fuel injectors and valve covers with these heads?

Yes, these Edelbrock cylinder heads are designed to be fully compatible with all stock Duramax components, including your factory valve covers, water crossover, injectors, and spark plugs. The injector cups are integrated into the castings for LB7 applications.

About this part

Product Details

Starting with the A356 aluminum casting, these Edelbrock cylinder heads are heat- and pressure-treated to reduce porosity and increase strength. This is crucial for the demanding environment of a diesel engine, especially when you're looking for improved performance. These heads are designed as a direct bolt-on replacement for your 2001-2004 LB7 Duramax 6.6L V8, meaning you can swap them in without major modifications to your existing setup.

Edelbrock has engineered these heads with a thick 15.5mm deck, which is built to handle increased cylinder pressures common in performance diesel applications. The intake and exhaust runners are shaped to optimize airflow and swirl, but there's also extra material in the deck and port walls, giving experienced builders room for custom porting to further enhance flow. Integrated injector cups are included for LB7 applications, and all factory components, like valve covers and injectors, will bolt on without any issues. Plus, they're CARB legal, making them a solid choice for street performance upgrades.

These cylinder heads are cast, machined, and assembled right here in the USA. They are also treated with a Hot Isostatic Press (HIP) process for added strength and heat-treated to T7 hardness, ensuring they can withstand the extreme operating conditions of a diesel engine. The raised rocker valley also adds water volume within the head, contributing to better thermal management.
