The LS Family of GM engines has continued our 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 heads can be installed on any 1997-2005 LS Family of 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. Our complete assemblies come with bee-hive valve springs and light weight hollow stem valves—innovations that our competitors have had to copy to catch up to our designs. We’ve already done the validation of these heads in competition in our show room stock C5R Corvette racecar, so you can be assured our LS6 race heads will live up to your demands.
