Hi,
Being in CA I have a more limited number of options for power increases (CARB ). Has anyone done a LS6 (CTS-V Motor) with just AFR 205 heads, and if so what were the gains?

Second question how will these heads perform with a magnacharger?

will the car have bolt ons as well?

I think it would be a fair to assume so. I wouldn't slap some heads on without doing the bolt-ons...but you never know.

It has a K&N Intake kit, and Magnaflow cat back. I have not seen any CARB legal headers. I'm looking at options in regards to higher flow cats.

Shorty headers are your only legal options.

P-1sc procharger or magnacharger!!! I can't see the AFR heads making much more than the LS6 heads maybe 20 MORE HP.

Do you have the AFR heads or are you going to buy them? port the ls6 heads.

shorties are it and stock cats are the only cat CA will allow you to run, high flow are off-road use only. why not some 243 heads through a sponsor? my heads have better flow numbers than the TFS 220 heads just sayin
