Car is a 98 Z28 automatic with stock cam. What heads besides the AFR's 205 (too pricey for me) will be a good choice for some additional RWHP and still be smog legal?

 

stock heads work pretty well with a stock cam.

If you do some searching, you will find that a cam swap will yeild better horsepower than a head swap at this point. If you are dead set on doing the heads first, take a look here -->

Patriot heads will probably be your best bang for the buck

 

thanks for your input. Patriot Heads sounds good. I will look which sponsor carry them.
