Presence or absence of lubrication can change recommended torque spec by a factor of 2 or more.
My pentastar spark plugs are specd at 18 lb-ft. But it doesn't say anything about lubing the threads. So I have to assume it's specd dry. For an aluminum head, I would normally use anti-sieze, but if I do that, does it mean the 18 foot pound spec is invalid then? I don't want to over torque or strip the head either.
