Aluminum heads should be torqued. The plug will torque only to 7-10 ft. lbs.. I have removed my plug hundreds of times through the years without incident. Most people tighten the plug way too tight and that is why the threads strip out. Can't tell you how many threads I've repaired on my sons engine. I now have him torque everything until the time he knows the tightness just as well as he knows to breath. I never have used anti seize but I am always pulling the plug but even on customers buggies or whatever I have never had a seized plug.
