I talked to an Autolite spark plug tech person and he told me dont use it, it causes fouling, misfire, etc. I run Aluminum heads on my drag motor. The only way i pull any plugs out is when the engine is cold, the next day. I never remove plugs to look for correct jetting, i jet for best MPH. I have removed plug #1 for TDC after a pass but will not do it only if i really have to. Save the heads and threads, remove only when cooled down or next day.
You are running a motor that gets the plugs pulled frequently on a regular basis. And you pull em cold... I'm talking about your typical car that folks put plugs into aluminum heads and leave em for 50 to 100 thousand miles and never pull em. Do that bare, and when your mechanic pulls em ( hot ) after 3 or 4 years, there is a very good chance that he will get more than the spark plug to come out. Those guys dont wait for a motor to cool, they get paid by the book, or by the hour and don't care. If they get to sell you rebuilt heads, all the more work for them. What ever works for you is great, I just find a SMALL AMOUNT, properly placed works good. And the plug won't misfire if its only on the threads, and just a dab. The ground will still be fine thru the seat where the lube isn't. It can't foul the motor if its a very small amount, and not past the first or second thread as it wont ever get into the motor. it will be trapped in the threads. If ya goober it up like a wheel bearing, thats a different story.
