GM Performance Parts L76/L92 Series Cylinder Heads

Product images may differ from actual product appearance.

The L76/L92 Family of GM engines has continued GM Performance's tradition of raising the power potential of the legendary small-block V-8. The LS6 cylinder head came as standard equipment on the amazing 405-horse Z06 Corvette and the 2005 Corvette with the LS2 engine. These L76/L92 heads can be installed on any 1997-2005 LS Family ov V-8 engines (except 4.8L & 5.3L versions), and the GM Performance Parts engineers have even designed fully-CNC-ported versions to get your late model GM engine screaming right along. GM performance's complete assemblies come with bee-hive valve springs and light weight hollow stem valves - innovations that their competitors have had to copy to catch up to their designs. They have allready done the validation of these heads in competition in their show room stock C5R Corvette racecar, so you can be assured their LS6 race heads will live up to your demands.
