Introducing the GMC Sierra Cylinder Head - Edelbrock Performer, specially engineered for the `01-`16 6.6L Duramax Diesel V8 engines. A direct bolt-on replacement, this cylinder head enhances your engine's efficiency and durability, making it suitable for both street and off-road applications while remaining 50-state CARB emissions legal.

The Edelbrock Performer Cylinder Head offers superior performance by capitalizing on the swirl motion essential for diesel engines. Unlike typical gasoline engine heads, this cylinder head increases volumetric efficiency without compromising swirl ratio. This ensures optimal air intake, promoting a clean burn and meeting stringent emission standards. Cast from heat-treated A356 aluminum, each head is pressure-treated to reduce porosity, strengthening its fatigue properties for those extreme diesel demands.

Features

• Heat-treated A356 aluminum for enhanced strength and reduced porosity.
• Optimized intake and exhaust runners to boost airflow and swirl.
• Direct bolt-on, compatible with stock Duramax valvetrain components.
• Extra deck and port wall material for custom porting and reinforced deck strength.
• 50-state CARB emissions legal (E.O. #D-215-102).
