Hotter Spark Plugs?

Just what exactly does that accomplish? I have an '83 Olds with the Buick 3.8L fouling the plugs from one day to the next. Oil is getting in there apparently. I have been told to run hotter plugs to help until I can fix the oil issue. Does running hotter plugs affect the engine in any other ways?

Can cause premature plug failure and at the extreme cause detonation, which can damage a piston, for a short period of time, not pushing the engine it should be ok, but you may be if for a big job on a 25 year old car!
