Only a 100 bux for the CNC, i oredered my heads last week and i was told they all ready shipped and nobody offer that service to me 
. I didn't even know it was avaliable until now. Nothing like leaving power on the table for a 100 bux. How much better are the CNC one. Looks like i'll be giving Jason a call first thing monday morning.

As for a large-chamber head, we could setup a set of 6.0L heads using the same ports. Only difference is you'd have a 72cc chamber instead of the LS6's 64cc.
The price would be the same as the LS6 for a set of 6.0L heads setup respectively.
Let us know if y'all have any other questions!

I just picked up a TSP 231/237 cam this week. I plan to pick up these heads with the PRC dual springs in about another month from you. Great to see these results!

The 6.0L heads would cost just as much even though the cores cost alot less???? Are you sure there wouldn't be a $200-300 price break using 6.0l cores?

I waited for A MONTH FOR THESE HEADS ALREAY. And then you make them better. The valve job on mine doesn't look very good ( tons of ridges With tooling marks at .40.) These heads we're not even lapped.

I didnt have the CNC valve job either. Nice results guys, Im getting ready to strap mine back on the dyno after some tuning with EFIlive. I expect at least 440rwhp, they made 432 without a tune. After, I may just throw a Fast 90/90 on top to see just what I can really make.

Great gains Buford! You must be really happy with this setup for only paying $1000 for the cylinder heads. My hat goes off to TSP for finding what these heads really needed. The added compresion seems to have really helped the low torque figures we were seeing lately with these heads and combined with the new cnc comp valve job these heads look like a great budget head producing big time HP numbers. Congratulations Buford and Jason at TSP!

The valve job without the cnc valve job upgrade is the stock valve job. The stock valve job still works very well, but the cnc valve job gives us better p/v for extra decking, and a little better air flow. We're working on some pretested combos for guys wanting a h/c combo to just bolt on & run. I'll keep you guys posted. Steve shoot me a PM & I'll see about your heads

Since I run a sprayed motor how much higher is the compression with these heads or is it even negligible? Also what about running a Torquer V.2 with these heads, any possible p/v issues?

Your gains are very believable in my eye's. We've used alot of stock valve heads that kill the hogged out heads alot of company's sell.
I'm installing my old heads on another car which are mild ported Z06 heads.The last 2 cars gained 45rwhp/35+tq with these heads.
Good to see PRC catching the wave
