The DC22 cam has the same intake profile as the DC24, but a smaller exhaust profile. Adding exhaust duration moves the torque peak up. It also increases the overlap. Since mid range performance and passing emissions are a priority, I would stick with the DC22.

Very lean mapping leads to higher NOX numbers. Does your states emission test include a NOX test?
