97-04 LS6 CNC Ported Cylinder Heads (Street Use)

If you have a 5.7L or 6.0L Gen III V8 (LS6 design) engine and want to improve the power output, bolt on a set of new GM Performance Parts CNC-Ported LS6 cylinder heads. The heads have the same CNC port as the race heads, but the deck has been planed just enough to maintain the production 65cc chambers giving a 10.5:1 compression ratio. Loaded with premium hollow stem stainless steel valves, Cr-Si ovate wire valve springs and other production components these heads will support 500+ horsepower.

Note: Must use new head bolts on installation & 97-98E cars must update valve covers to later style. No Discount.
