some say yes; other sez no.
They all have their points though.
Frankly speaking, I have not used any anti-seize on any Alu heads for 20 years of servicing cars, citing the following:
(1) with OBD-II emissions systems so sensitive to fouling or contamination of emissions components, I would not tempt fate by dabbing my spark plugs with lead-based antiseize
(2) I always torque all the spark plugs properly to factory specifications, no exceptions to the rule (and no guessing)
(3) all spark plugs and type, be they iridium, platinum or copper (it's actually nickel, but with copper core/insert), I typically pull them off every year or 1.5 yrs for inspection and then re-torque them afterwards. None would seize inside the heads for as long as they let me service/maintain their vehicles.
(4) don't leave any spark plugs threaded inside the heads for too long for the deposits from combustion process will accumulate at the end (close to the electrode) of the spark plugs, causing all kinds of issues such as difficult to un-do,etc. and the likeliness of cross-threading/seizing on the head will be high. I've experienced it once with a head with original spark plugs in it for 6+ years. Took me a better part of 1/2 hr with lots of lubricants, etc. in order to free them (4cyl). replaced them with fresh ones and they all went in like a breeze.
So, you got my 2c's worth. It's up to you to decide now.
