Replace the right cylinder head on your 2001–2004 GM 6.6L Duramax LB7 with the Fleece Performance FPE-61-10001-P-CL Freedom Series Cupless Cylinder Head. Built from a new aluminum casting, this cylinder head eliminates the factory-style injector cup design to simplify assembly and remove a potential source of injector cup leakage.

The cupless injector bore design eliminates the need to install separate injector cups during engine assembly. This reduces installation complexity while removing the possibility of future leaks between the injector cups and cylinder head.

Each Freedom Series cylinder head is assembled in Fleece Performance's engine facility and is CNC machined with a multi-angle valve job. New valves, valve guides, valve springs, and valve seals are installed before each head is thoroughly inspected, pressure tested, and leak tested for dependable operation.

Designed to meet or exceed OEM specifications, this fully assembled cylinder head is well suited for daily-driven and towing applications. It is supplied without a core charge, eliminating the need to return your original cylinder head.
