First of all, you need to get it tuned for all those mods you've installed, otherwise it will keep running like ****. Second, open headers will make you run extremely rich since the O2's will be picking up open air since there isn't enough piping after the sensor.

open headers = high o2 content coming back into exhaust pcm sees o2 adds fuel = rich
big cam= causes lower vacuum = pcm adds more fuel
so you have 2 biiiig factors of adding a ton of fuel
did someone say something about maybe a tune?

Also if your running a stock converter in the car, you might want to step up to something a little bigger. That cam is starting to touch the territory where a stock verter could be bad.
