TSP CNC LS6 vs Livernois CNC LS6 heads

Our PRC Stg 1 LS6 has been proven on the boards, run a search & I think you'll find really good results. We use complete cnc porting & cnc valve job to create the most consitant product possible. You guys might want to jump on texas-speed.com & checkout the video of the cnc valve job being cut on a set of stage 1s! It's really a amazing setup that helps us to make sure every set performs exactly to our expectations. The PRC port design allowed us to sink the valve a few thou giving us the ability to deck the stg1 head .015" getting 62cc chambers while still keeping stock p/v! We currently have a few different new camshafts being tested right now that will help to keep dcr up especially when they are used with this new cylinder head configuration!

How long until the new camshafts are available? Can you give us any more info on them (lift, duration, lobes)? I'm ready to get my car back on the road again

I am ordering my Livernois Stage 1 LS6 heads this week..
I am currently running a 232/236 .595 .601 on my A4 with a 3500 stall...
True duals "dumped"- 388hp-380tq... i have run them out the rear now and last dyno was 377hp & 372tq... I am running full bolt ons...
I should have the heads installed by June/july time frame with a full tune...

my car is a daily driver with 210K on the clock..
Gotta love these LS1's...

I made 435/400 with the TSP LS6 heads stock valves/unmilled stock gaskets and a baby 228/228 114 + 4 XER cam....You can keep velocity up with a bigger port as well, its all in the port design. That was also through the LS6 intake and WITHOUT the new competition valve job. These TSP heads ROCK! I just purchased a Fast 90/ LS2 TB and Im installing it this week. New numbers soon. Im expecting around 450rwhp/410 rwtq.....

That was with our 5 angle valve job, 2.00"/1.55" oem valves, and our Patriot Gold dual spring kit. This price also included oem head bolts and shipping.
