7's in the leadings and 9's in the trailings. It won't make enough heat to merit going to a colder plug.

Depends on your ignition system. I have ran 10's leading and trailing with MSD 6AL's with no issues. Daily drivers with full bridge motors.

That's not because of the plugs. It'll be because of something else if it is true that your power should be higher than actual.
