I always use anti-seize whenever I'm installing spark plugs of whatever type for several reasons:
If installing spark plugs into aluminum heads, it helps prevent pulling the threads out with the spark plug during removal.
It seals the threads to help keep the combustion gasses inside the cylinder.
It helps conduct heat.
It better grounds the spark plug to the head.
I'm sure there's other things I could write down as well, but this is sufficient. Anti-seize does a lot more than act as a lubricant. As long as you don't over tighten a spark plug, you should have no fear of using it.
