Hello JFP, speaking of anti seize..
I always put a very small amount of thee grey anti seize it on the spark plug threads (have don it for many years with the aluminum heads) and never had an issue with this practice, but I remember reading somewhere that on the plugs you should only use copper anti seize to help maintain a proper grounding, what do you use for this application?
