This custom head stud kit is for the LS9 engine specifically, opposed to using the LS3 kit and trying to put extra washers in it.
ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. They are heat-treated prior to thread rolling and machining. ARP Pro Series kits are also available with 12-point nuts, and all kits come complete with hardened parallel washers for an even load distribution and accurate torque readings. With hundreds of models ready to ship, these cylinder head fasteners can be ordered for virtually any style engine.
