Beg to differ.

On an aluminum head you want the engine stone cold when pulling the plugs. Heat expands the metal, which makes a tighter fit. Pulling plugs on a stone cold aluminum head minimizes the chances of pulling the threads out.

If they are already siezed, I guess anything is worth a try as you'll end up having to helicoil the plug holes anyways. Use anti-seize and a torque wrench when installing spark plugs.
