Secondary air for smog?

I keep getting the same codes telling me that the car isn't getting enough air on cold start-up on both banks. I replaced the air pump, and I can hear it come on every time I start the car. I've replaced the check valves to both sides, and I still get the same thing after I clear the codes and drive it. Both banks are not getting enough secondary air. I even ran an endoscope camera into the air pipe and into the head. There is carbon but not much at all. The camera can go all the way to the other side of the head with no problem. The car runs great, but I can't get it to pass OBD2 standards. Any help would be great.
