PRC LS6 Heads Get A Face Lift!! 225cc Runners!!! As most of you guys know we've been working really hard recently to rework all of our cylinder heads to improve power, performance, and value! The LS6 head is the newest cylinder head to go through these revisions. All future LS6 heads will ship with all the new features at NO EXTRA COST!!!
We just finished up the newest revision of the PRC LS6 cylinder head! The new cylinder head features a new smaller intake runner (225cc), new bigger cfm exhaust port, & aftermarket rocker arm clearances!!
The new intake port was reshaped to provide the same great airflow you've come to expect from PRC with a smaller runner for increased velocity & throttle response!
Here's a few pics of the new ls6 intake port. The port in this pic goes 310cfm @ .650 lift!!
The Exhaust Port was also completely revised from top to bottom! The all new exhaust port flows as much as 10cfm more air than the previous port with the same valve size!
NOTICE IN THIS PIC THE ALL NEW AFTERMARKET ROCKER CLEARANCES & CUSTOM PRC ENGRAVING!!
Improved airflow, improved features, smaller runners all available at the current special price of $949.99 with stock springs!!!!

Also I was pretty stuck on the revised 5.3l heads but now that you revised these heads would they work better with my 233/239 cam over the 2.5 5.3's?

Ok so school me on something. I'm really wanting to buy a set of your heads. I feel stupid calling and asking such newbie questions.
I'm planning on running a stock shortblock with..say.. these heads, FAST 92mm intake, ported 90 DBW throttle body, SVO 30# injectors, your MS4 cam, long tubes, 4K Yank through a built A4 and a Currie 9" with probably 3.90 gears and true 3" duals.
Should I run stock rockers?
Good combo? and advice?
