Any anti seize will work - just use it sparingly.

 

which ever anti sieze you use, just use a minimum amount, like the man said, on th first couple of threads

 

I have used anti-seize on these things for the 38 years Ive been on em....but put a VERY LITTLE on your finger and wipe on threads lightly, just enough to show a little color. You dont want to get any into the chamber so go easy

 

I use the Nickel based, it has a heat rating good to 2500 degrees, I doubt that that temp is ever exceeded,

The copper is rated to 1800 degrees (you still probably not reach that temp either).

BUT, I only use the Nickel because that is what I can get free.
