Another point not mentioned enough about silver and copper anti seize is that it increases torque values by 20% so when you torque the spark plugs you should use 20% less torque to prevent breaking the plugs or stripping the soft threads in the heads. It's also worth mentioning that alot of modern spark plugs already have a nickel anti seize coating and some manufacturers recommend not using any sort of anti seize. I'm not sure if the Delco iridium plugs have this coating, but I always put a little on the threads anyway.

Yes, use anti-seize on the threads.

So, what happens the next time you change plugs and you have dried and gunked up old compound in the head threads? Surely using a thread chaser to clean out the head would let debris into the cylinder. Not trying to over think a spark plug change but the yeah and neah seems to be devided. Since I'm changing them and the wires because not for high mileage ( car has 25,000) but since they are original and 15+ years old I feel it's a good deal over do. All my other (go fast) cars are steel heads. Only a good plug socket and ratchet is required on those. Car runs great for last 15 yrs. just some p.m. Is due now. Thanks for all the input.

Another vote for anti-seize. Anytime you thread steel against aluminum you should. Aluminum is smeary and will gall against steel and get stuck. I'm like the grandma in the Frank's RedHot commercial with never seize. I put that s--- on everything!

“Copper conducts” like aluminum doesn’t?
The heat in a head dictates higher heat material as exhaust temps reach past 1k degrees on a hot run. The silver anti seize is more apt to turn to dust.
Use whatever your book tells you, I’ll use copper like I have for Decades on my engines.

The heavily built V8s (many forced induction) I’ve seen I’m sure were all screwed because copper anti seize was used?
Umm, no. They’ve all been beasts.
