Default What else to change out during header install?

Headers are going on Tuesday....got to thinking maybe while the system is apart might be a good time to change out some things. I've seen some posts where it was a good opportunity to put in new O2 sensors, or spark plugs...however, my car runs fine with 50k miles, and the Vette mechanic said it isn't necessary unless I was throwing codes, so whatcha think?

I would replace the plugs with that kind of mileage on them.

The 02 sensors, eh...sometimes best to let a sleeping dog lie.

Good time to do a better tunnel plate while you have exhaust off.

I think it's really up to you. When I installed my headers, I went ahead and did the plugs and wires. Had to remove them anyway, so I decided to re-install new parts. Did not change the sensors, just moved the rears to the front. Also installed the "Koolsox" on the wires. Had the car dynoed and the rear sensors programmed out. My personal opinion is with 55k I would go with new plugs and wires.

New steel LS1 exhaust gaskets, plugs, wires and Kool socks for good measure. Plenty of heat wrap tape on wiring in critical areas.

Make sure you get one with the thermal sheild above and beyond the ceramic coating...it makes a difference on console temps.
