Honda Repair: replacement fuel injectors, dc sports headers, cold air intake

Question
I have a '94 Civic EX with the SOHC VTEC D16 engine.  It failed the NO2 part of the emissions test.  I've been told it's most likely due to a stuck injector.  I've put a cold air intake, K&N air filter, DC Sports headers/catalytic converter/exhaust.  The car has 120,000 miles.  The kits to overhaul the injectors are nearly as expensive as replacing the injectors.  However, I'm confused about which ones to get.  Won't be going turbo/nitros/supercharger and I hear the stock injectors aren't at their max on these cars.
What would you recommend?

Answer
If your going to continue to run high performance on the car I wouldn't run stock injectors,maybe something between stock and racing since your not running turbo or nitrous,the only thing I really know what to tell you is try checking out nopi's web-site or jc whitney's site that might give you a better understanding,unless you just want to replace the one that is clogged or sticking and just save up your money and get better injectors foe performance
