Description
Industrial Injection stock reman LB7 cylinder heads with screw-in torque-lock injector cups for 2001-2004 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 6.6L LB7 Duramax. Sold as a pair, fully assembled and ready to bolt on. Same reman process as the standard PDM-LB7SH, with the cup upgrade installed at the time of build.
Each head is jet washed, glass beaded, pressure tested, and visually inspected. New high-strength heat-treated iron-based valve guides are installed (Rockwell 22 C scale) and premium nickel-based non-magnetic valve seat inserts are used as needed. Guides are diamond honed to exact size, the head receives a multi-angle valve job on a Serdi 100 machine, and the deck is surfaced on a Berco mill with the finish matched to the head gasket spec. Final assembly uses new valve seals, new valve springs, and the screw-in torque-lock injector cups.
