I've heard that before, yeah. But, I wonder is that more of a concern in an iron head, where you're applying quite a bit more torque.
If you factor in a 10 or 15 percent increase in torque from anti sieze, at 11 pounds, I still think you're in a safe zone with an aluminum head.
Just apply conservatively. It only takes a dab. Or, use none at all. Assuming you intend to change plugs regularly, it's likely seizure wouldn't ever be an issue.
