I pulled the plug yesterday applied anti seize, and the threads felt fine. They also felt fine earlier, but I figured, anti seize now, no worry later. And I'm pretty sure the threads are good. Bigger plugs can take some torque, and I didn't give them much. Like I said wrist tight. I'm pretty dang sure I didn't s screw myself. No pun intended.

Anti seize on plugs is always a good idea
