Precision Race Components L92/LS3 64-72cc Stage 2.5 Cylinder Heads Fully CNC Ported & Assembled With Factory GM 2.165" Intake Valves and 1.59" Exhaust Valves, TSP Dual Valve Spring Kit with PAC Racing Springs & Titanium Retainers - Good to .660" Lift.  Kit Also Includes TSP Hardened Pushrods & Your Choice Of Camshaft!

When selecting your camshaft, please keep in mind that the largest camshaft you can run on a factory LS2 or LS3 short-block is our 235/248!  Anything larger will require you to cut valve reliefs in your pistons!  All of our camshafts were designed on our SuperFlow 902 engine dyno on a factory LS3 engine, and the camshafts listed are our latest LS3 creations.  They were created, ground, and tested all in-house!  These camshafts are designed for maximum power on a stock LS2 or LS3 short-block without any piston-to-valve clearance issues.
