Default Legal heads and cam upgrade mod

Reading alot of post regarding modifying our LS1 and resulting CA getting the strict low down on us. How about cam and head upgrades. Will CA Smog Check ever notice a mild Cam and Head mod? hailing up in the bay area Northen California, what shops are good out there that can install legal cam/heads?

They're not technically legal. I'm not sure as far as heads go but you can definately get a TR 224 cam on a 114 LSA to pass a CA smog test. Just tell your tuner you want it to pass and it won't be a problem at all. That, shorties, a catback, and a lid is about as far as I'd go if I didn't want any worries... but that's not quite the rout I took since I'll be moving to NV soon - good luck.

You can get a good S2 set of heads, that's not the problem in the smog part. It's the cam that can get ya

That makes me nervous. What if I go with a Supercharge system?

The Procharger systems utilizing the P-1SC impeller are CA smog legal and can make you good gains. Don't expect QUITE the results everyone else is getting since your stock exhaust will inhibit your power.

TR 224 will pass but 244 seems a bit far fetched,

Thank You. Drive Thru,

Heads dont really have much of an effect on emissions - its the cam like Ken said. The 224 224 114 is the cam to go with, its been proven to pass with a good tune. Others have had bigger cams pass but that can get kinda sketchy without a dead on tune.

use the vinci/crane "boss" cam if your worried about cam. The a good set of aftermarket heads and some shorties . or thunder racing has the emission friendly cheater setup that requires no headers
