From: Montreal Drive it like you test it !
You have a near stock engine. I would use the GM 41-985. They should be pre-gap at .40. If they are not, do not re-gap, but have them replaced. No anti-seize is required since they are coated. I drop of Mobil 1 on the thread will make it. Removing the spark plug wire is not easy. I disconnect from the coil then I turn the rubber boot at the sparkplug end and the wire comes out. Torque the plugs at 11lbs. I remove the air pipe to make some room. Cylinder #1 & #7 are the more difficult.
Tuner can use other plugs because they can tailor ignition timing to their specs, as well as the cam, flow of cylinder heads, tumble within the combustion chamber and the like. But for a stock engine, go wit the 41.985 since the PCM is set up to work best with these.
Some more on my website http://pages.videotron.com/vette747/ and scroll down to the "Spark Plug & Wire on Z06" link.
