Precision Race Components Aftermarket Casting 6-Bolt 260cc Fully CNC Ported LS3 Heads. Assembled in the USA

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.

***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!***

NEW PRC 13-Degree Valve Angle LS3 Castings

All PRC cylinder heads are extensively researched and tested. The all-new PRC aftermarket casting LS3 cylinder heads are designed to flow considerably more than a gm ported casting while keeping the port sizes smaller for improved port velocity. The result is a cylinder head that is smaller than a stock GM LS3 port and moves more air than any other ls3 cylinder heads!

The all new PRC aftermarket casting LS3 heads are the perfect option for customers looking for the ultimate in LS3/L99/L92 cylinder head technology

The 13-degree valve angle will allow for the ability to run more compression and larger camshafts thanks to additional piston-to-valve clearance!!
