Cam vs Rockers...no offense here, but if your not mechanically inclined (I am guessing due to this thread and your comments on how hard it was to change the plugs) I would not even think of doing a Cam...rockers you might be able to do...but it will be a long PIA process...if you do go with rockers, research, research, research, ask lots of questions, research, research, ask more questions...repeat above process till you cant possibly think of anymore questions or possible snags you might run into, then proceed slowly, and post your questions as you do it. Plan on it taking a weekend to do and if you can get help from another member or a mechanic friend...DO IT. I only say all this not to harp at you, but rather as a warning...Rocker and Cam installs are NOT places you want to make ANY mistakes. Leaving one bolt or nut not torqued down, or one thing not put back as it should can cause severe engine damage and I would hate to see anyone not 100% confident/comfortable with doing the job get it all done thinking they did a bang up job and screw their motor.
Again, NOT trying to belittle you or your mechanicals skills...just a word of caution.
Oh and your fine with the plugs in there, it won't hurt the car at all to have them in on a stock motor...little cold of a heat range maybe and gas mileage may suffer a bit (but not compared to the state your old ones were in), but it will be fine till the headers/3.4 pully go on.
