Edelbrock Announces New High-Performance Cylinder Heads for GM 6.6L Duramax Diesel Engines


Edelbrock, a leading manufacturer and distributor of aftermarket performance parts, enters 2019 with its first-ever high-performance cylinder head designed specifically for the diesel engine market.

The all-new Edelbrock Cylinder Heads for 2001 through 2016 GM 6.6L Duramax Diesel V8 engines are a direct bolt-on replacement for any street or off-road application where higher levels of performance and durability are desired. These aluminum heads come complete straight out of the box and are designed to fit all four variations of the Duramax engine that were offered in the popular Silverado and Sierra pickup trucks, as well as Chevrolet and GMC 2500/3500 HD trucks between 2001 and 2016. Edelbrock’s new Diesel Cylinder Heads are compatible with all stock Duramax valvetrain components, in addition to valve covers, water crossover valves, injectors and plugs.

Each A356 aluminum cylinder head casting is heat and pressure-treated to reduce porosity while also increasing strength and fatigue properties. Intake and exhaust runners are designed to optimize flow and motion of air in the cylinder. Engine builders and head porters will also appreciate the extra deck and port wall material for custom porting and deck strength. Best of all, the new Edelbrock Performer heads are CARB legal making them the perfect choice for a street performance upgrade to any Chevy or GMC Duramax Diesel engine.
