NEW PRC LS6 CNC Cylinder Heads $849pr!!
I'm proud to announce that we just finished up the brand new PRC LS6 cnc program. The program finishes really nice & flows better than any LS6 program I've ever flowed on our bench! These cylinder heads flow well over 300cfm @.600 with stock size valves!
Here's some flow data from the new port:
.300 204
.400 253
.500 286
.600 306
I'll get some graphs printed up for anyone interested. These cylinder heads will be complete with stock 2.00" & 1.55" valves, LS6 yellow springs assembled & decked to your specs. We have a few sets of these heads in stock & ready go!
Upgraded bigger valve heads & upgraded springs are also available!
P/V will remain stock so you have no worries running these heads with really large camshafts

Are these factory GM 243s with your port work, or an "LS6 style" head?
Any core charge?
When you say "stock valves", are these Z06-type lightweight? Thanks!

On your site it says 2.04 1.575 valves for $1199, Can i get these heads bare with that valve size so i can purchase my own valves? If so what price will they be? I am just wanting the heads bare with the valves cut to fit that size of valves.
thx rob

I'll get Jason@TSP to update this thread with info/pics as he is more in the "know" about the cylinder head side of TSP. Just a few quick answers to questions I know.... We did a set of 6.0L heads for a turbo setup last week, it did have bigger valves though. With a very conservative valve-job they flowed ~318 @ .600, I would imagine a little more can easily be had with some minor work.
I'm pretty sure the price is the same with/without stock valves/springs. We do have pricing add-on's for custom valve-jobs (to your valves), PRC dual-springs, bigger PRC valves, and also don't forget the heads/cam packages.

Damn thats a good price,these are aluminum right? Do these start out as lq9 6.0 liter heads ?Or are these a seperate casting? Or are they ls6 heads to start with. I was going to upgrade my springs and pushrods for about 400-500 dollars,But may as well get the heads for 850. Wow!Yall think these would work good with a procharger? What cc are these heads and what compression ratio would I end up with on a stock 04 ls1 gto motor? I am ready to order.

They are LS6 castings The heads are 64cc & get you 10.5:1 compression
