Kit Includes:
- (2) LS9 Head Gaskets (PN 12622033) – best gasket to use on most LS builds
- (2) Sets of 2005+ Head Bolts (all same-length bolts for easier installation)
- (16) Delphi LS7 Hydraulic Roller Lifters
- (4) OEM-Style Lifter Guide Trays
Notes:
Prior to 2004, Gen 3 and early Gen 4 LS engines used head bolts of varying lengths. Starting in 2005, GM standardized all head bolts to a shorter, same-length design. Please confirm your engine’s head bolt style before ordering.
NOTE: On these engines it is highly recommended to clean out the head bolt threads in the block with a chaser such as ARP 912-0011 (click here) due to the thread compound that was used on the factory bolts. Failure to do so can result in new fasteners stretching or breaking before reaching final torque.
