as long as there is no check engine light, everything is fine. as soon as one fails or the engine runs too rich for the o2's to adjust the mixture, the light will come on, so I will say all's well, unless.

why are you visually inspecting them anyway? you can't tell anything with a visual. you need to read voltage's and see if the heater is coming on, all done with a scanner. don't worry unless the ck engine light comes on

I was taking the header off for a different reason. Nothing wrong with them...at least no lights going off. Just thought they might look a little on the dark side. But I'm differently no expert at this.

Thanks guys.
