AFR heads carry a 50 state CARB # so that would be OK in CA. If you want the appearance of stock, then modified GM castings would be harder to detect on a visual inspection. To visually remain compliant, those appear to be your two options. As far as the cam is concerned, I have read and spoke with guys from CA and 224 on a 114 is about the limit and still pass smog in CA.
