Make sure the anti-foulers are very tight or Jbwelded. The last thing you want is for one of those to be stuck in the sparkplug hole while the rest of them unscrew from one-another. <<< would be a nightmare and is a pita to fix.
Also put a little grease or wd40 on the rubber boot inside the sparkplug socket, so that doesnt get stuck on the plug when you go to pull it out. Or tape it.
