That’s right, Edelbrock, one of the industry’s leading companies in the gasoline performance world has stepped into our arena. We met with the team at Edelbrock a few weeks ago in Southern California to discuss some future projects, and boy, do they have some great stuff coming down the pipe. Hot off the press, getting their foot in the door is their new Duramax Diesel cylinder heads for on and off-road use. These heads are a drop-in replacement, ready to go units that perform better than stock but still maintain the emissions quality they must pass.

These cylinder heads feature intake and exhaust runners that have been optimized to increase airflow. In fact, it Edelbrock is claiming these heads flow 20-percent more than a factory head. Each cylinder head is cast from A356 aluminum us the Hot Isostatic Pressing method. By heating the raw castings up to 900-degrees in a pressurized chamber, they compress the casting to remove any trapped gases and internal porosity. This results in a much stronger and denser casting with virtually the consistency of billet aluminum.

With that being said, this means the HIP-processed cylinder heads have up to three times the fatigue life of conventionally-cast heads. Not only do these heads hold more life, but they have smoother machined surfaces which is great for an engine with such high injection pressures and compression ratios.

Edelbrock Duramax Cylinder heads are fully assembled with valves, valve springs, locks, seals, and retainers, and are 50-state emissions legal (CARB E.O. number D-215-102).
