FPEFPE-61-10001-D-CLPulling the driver side head on your LB7? Put a new one back on, not a tired used casting with injector cups that will leak again.
Fleece's Freedom Series head for the 2001-2004 LB7 is built from a new casting with a cupless injector bore. That saves time and money: no injector cups to install, leak, or worry about. It's made for the daily driver or a towing truck.
