Check valves

I have new check valves and still pull P 1416 H C right bank check valve code.
I have Dougs Headers and Donaldson cold air intake.
Concord Chevrolet has been trying to fix this problem for 2 months. New check valves, new oxygen sensors, new ECM and still pulls 10 PCM P1416 HC code.
Any ideas on how to fix this?
