Edelbrock 79029 Performance Cylinder Head

Put the Edelbrock 79029 Performance Cylinder Head on your 2001-2004 GM 6.6L Duramax to increase performance, durability, and airflow in your engine. Made by one of the most legendary names in automotive performance, this cylinder head carries the same build quality that you've come to expect from the name Edelbrock. Designed as a bolt-on replacement for stock, or performance applications. The 79029 Cylinder Head works with all of your factory valvetrain components along with your valve covers, injectors, and glow plugs.  

This Edelbrock LB7 Cylinder Head is heat treated to T7 so it can withstand the extremes of your performance diesel engine. The T7 specification heat treating results in a casting that is called "overaged". This "artificial aging" step is carried further than T6 which is the industry standard. This not only reduces residual stress in the casting, it also gives you a more dimensionally accurate finished product. T7 affects the tensile strength, compressive strength, and the hardness of the casting. This reduces the possibilities of cracks, dropped seats, or the head lifting in extreme applications.   

The intake and exhaust runners on this LB7 cylinder head has been designed to optimize airflow and swirl. For those race engine builders that need to take it a step further, this cylinder head has extra deck and port wall material so they can still be custom ported. The raised rocker valley adds water volume in the head, and the injector cups have been integrated into the casting. Edelbrock's Performance Cylinder Heads are emissions legal so they are perfect for a street performance build, or an all-out race truck! Sold individually.
