I was going to buy the Patriot stage II LS6 style heads, but would really like the Darts. Would you worry about using these heads in CA? How aftermarket looking are they, sitting in the engine bay?

 

They are pretty stealthy with regards to looks. There is a little "DART" on one end of the casting and "PRO 1" on the other. The end of the head doesn't have any large logo's like the AFR's so you would have to look close to see that it is an aftermarket head.

 

If you're really worried, get the AFR 205's, they are CARB certified
