Anti seize on spark plugs in aluminum heads?

never used it until I pulled the threads out of an AL Mazda head....If its AL it gets it. Even goosenecks on bikes. Just make sure you hand thread the plugs as far as you can before torquing them. AL head plug inserts work but you never know if they are gonna come out with the plug. I guess I should have thread locked them...28 years ago.
