first of all, antiseize is safe on aluminum. you don't use a lot, just a dab of ~3/8" dia and spread a bit.
dry thread but is free of carbon? In my early years of car experience, I avoided the antiseize compound on sparkplugs and getting in and out is very sticky and draggy (lots of friction). Aluminum is rather soft material, so soft that you don't typically use cutting oil/lube to cut drill aluminum. Sparkplug threads are steel and much harder
(relatively speaking for you material engineers out there) and can damage the aluminum if seized.
I mean you can thread chase the hole but that's only if the car is running really bad w/ carbon soots everywhere.

Antiseize is a lubricant and you'll have no idea how tight you get them but it will be over tight and risky unless you adopt a lower spec.
