A Viton O-ring is good for over 200 degrees C. A Teflon one is good for over 500. On my race car, I start with a hotter plug, warm the engine to temp, then change to the colder plug for the track. This eliminates the problems of fuel fouling. This is a common practice. Antisieze on the plug threads is good for even street engines.

P.S. work hard in Cupertino. I need my Apple stock back up to $150. Typed on my Powerbook, as my HP is half the speed.
