Picked up a set of Texas-Speed Ls3 heads ...
PRC LS3 & L92 CNC Ported Heads,
When all the pieces fall together this car is going to be a lot of fun, actually more fun.
Nice heads, I have used a few of PRC heads with nice results . Now you need a FAST 102 and port that 90mm tb
Make sure that you buy some ARP bolts as the GM bolts are stretch yeild, and therefore one time use only . I would also get a set of the Cometic head gaskets .

LS3 West Coast Cylinder Heads Swap - Head Games
Redline's Cam-Only '09 C6 Makes Over 518 RWHP With WCCH CNC LS3 Heads

It has been dubbed by many as a mini-LS7, and for good reason. Bone stock, our '09 C6 tester made a whopping 406 rwhp
on Redline Motorsports' Dyno Dynamics rollers. With a big cam, Kooks 1 7/8-inch long tube headers, Borla exhaust, VaraRam
cold air intake and custom tune, output jumped to 483 rwhp, not to mention well over 400 lb-ft of torque.
We couldn't help but wonder what the LS3 would be capable of with a good set of CNC-ported stock heads.
Thankfully West Coast Cylinder Heads was more than happy to comply with our wishes, as they have been running a well
planned CNC program on the identical L92 heads for over a year now. With these bad boys we were confident Redline tech
Jon Bettini's C6 would hit 500 ponies.
Follow along as GMHTP makes another trip up to Redline's pristine Schenectady, NY shop.
With the LS3 all buttoned up, the C6 went back on the Dyno Dynamics rollers. Despite the size of the runners, the gains were
all across the board. It seemed to take a few pulls for the PCM to "learn," but eventually Howard tweaked the tune using EFILive
to get rid of some knock at the top end (most likely from the sizable bump in compression) and we had an LS7-shredding 518 hp
and 452 lb-ft of torque at the wheels. That's a gain of 36 hp and 30 lb-ft of torque. Not too shabby considering how good the
heads are from the factory, and that this is only a stock cube motor.
406 RWHP bone stock ... This is the article that I read, and have a hard time believing those numbers in stock condition. If those number are true and not a fabrication for that shop, then achieving 430+ RWHP, which is at the high end of my expectation will be easy to achieve.
I guestimate that with all the things I'm doing, with a baseline of 380 RWHP, achieving 420 RWHP should be a realistic goal. Anything over 420 RWHP would be gravy.

My C5 that was 350HP stock with my mods put down 535rwhp, so with your mods and a starting
point of 430hp there is no reason you should not be in the mid 400's with the mods you have talked about.
Anyways post up with a dyno sheet when she is all done, if you get into the mid 400s you will love the power!
This 09 was set-up for road track, so we have no 1/4 mile times . It has a full Pfadt race suspension and was corner weighted . This vette handles like a dream
Now in comparison the yellow 07 Z06 that we cammed last year ran the 1/4 at TMP @ 11.3 on the Goodyears . Its a 520RWHP car .
Thx

I think Greg mean's 435RWHP
