Precision Race Components Aftermarket Casting 6-Bolt 260cc Fully CNC Ported LS3 Heads Assembled With Hollow-Stem Stainless Steel Valves as Standard, TSP Dual Valve Spring Kit with PAC Racing Springs & Titanium Retainers Good to .660" Lift; Kit Also Includes TSP Hardened Pushrods & Your Choice Of TSP LS3 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 camshaft! 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.
**You must have a minimum of a 4.00" bore size to run these cylinder heads!**
***If you purchase a Melling oil pump you MUST use a single-roller timing set! The Melling oil pump will not clear a double-roller timing set!***
