I need to know how much the mods on my car will affect smog.  I passed my last CA smog check easily two years ago.  Since then I have added max ported iron heads with 1.77 valves and a Comp 206/206 cam.  I will also be running the 3" cat that came with my THDP.  This cat worked great for me last time, but I know there is some controversy over whether it is actually the "right" cat for CA emission requirements.  Is the head and cam upgrade likely to cause me problems?  
P.S.
I do plan on replacing plugs with fresh AC42TS's and installing a new 02 sensor because of that leaded 114 octane that "accidentally" got into the tank.
