PRC LS6/LS2 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!!!!

Can this type of port be put in a 6.0 cylinder head? I know the chamber is different but correct me if I am wrong from what I gather everything else should be the same as the LS6 head.

Absolutely we can put it in a 6.0 casting. The price is even the same! 
They are 70cc chambers...

Jason, I've been trying to refer people to this head, but they can't seem to find it on your web site. Is there a catalog link you can post? They want to make sure they're getting the new CNC program and not one of the leftover 243 heads with the old program.

The 2.5 LS6 on the site are these. We aren't cutting the old ports anymore. I'll make sure the site is getting updated with all the current info and flow numbers! Thanks for the heads-up!
