Edelbrock proudly introduces its first-ever high-performance cylinder head developed especially for the Duramax Diesel engines. This brand new Edelbrock cylinder head is available for 2001-2015 Duramax Diesel V8 engines are a direct bolt-on replacement for any daily driver or high horsepower application where higher levels of performance and durability are desired. These aluminum heads come complete and ready to run right out of the box. They are designed to fit the different variations of the Duramax engine. Edelbrock’s new cylinder heads are compatible with all stock Duramax valvetrain components as well as valve covers, water crossover, injector and glow plugs.

Edelbrock Duramax cylinder heads are manufactured with a technique called Hot Isostatic Pressing (HIP). This aerospace process heats raw aluminum castings up to 900° F in a pressurized chamber (up to 30,000 psi) and compresses the casting to remove any trapped gases and internal porosity. During this process the casting is compressed to eliminate these imperfections. The result is an incredibly strong and dense sand casting that has three times the fatigue life and nearly the consistency of billet aluminum.  This also provides a better; smoother machined surface finish when CNC port and chamber work is applied.

Each A356 aluminum cylinder head casting is heat and pressure-treated increasing both strength and fatigue properties. Intake and exhaust runners are designed to optimize flow and swirl, but race engine builders and head porters will appreciate the extra deck and port wall material for custom porting and deck strength. Best of all, the new Edelbrock cylinder heads are emissions legal, making them the perfect choice for a street performance upgrade to your Duramax Diesel engine.

Features:

  • Extra deck and port wall material for custom porting and deck strength

  • Thick 16mm deck for increased cylinder pressures

  • Improved flow and swirl characteristics can deliver an increase in hp & tq and lower EGT's

  • 31mm exhaust valves and 33mm intake valves

  • Fully nitrided, stellite faced intake and (Inconel) exhaust valves provide high strength and hardness or for excellent wear and corrosion resistance

  • Designed, cast, machined and assembled in the USA

  • Castings are treated to Hot Isostatic Press (HIP) process for strength

  • Heat-treated to T7 for the extreme diesel operating environment

  • Raised rocker valley adds water volume in head

  • All factory components bolt on without modification

  • Injector cups are integrated into the castings(LB7 applications only)
