The heat range for anti-seize goes: Regular Aluminum, Copper, Nickel
Spring for the nickel anti-seize if you're going to use any.
As careful as people say they are I bet many apply too much of most any product.
My last 3 cars had aluminum heads. The first time I extracted plugs from each one the plugs screeched and howled.
Subsequent removals were quiet.
Actually, with my current car the screeching and howling began immediately so I stopped wrenching and oiled the plugs in their wells. then I "back 'n forthed" the wrench to lessen damage.
Another inconclusive post on the topic.....except for me.
