I'll say this (as I have many times before)... a few threads of engagement is OK, just whatever it takes.
I put my plugs in expecting them to leak and while watering the engine, I tighten the plugs only to the point that they no longer leak. Stop, not one more turn..nothing... the plugs will be fine and stay there until wrenched back out....
Been down that road and those threads will easily strip. Just tighten enough to stop the leak...
