aluminum anti-seize.
dielectric grease on the plug boots.
and torque the plugs!
work on cold engine, blow out plug area with air before removing each plug.
remove valve on drivers side, 2 10mm bolts and rotate out of way makes it much easier.

Anti-Seize, a light amount on the threads - use a old spark plug boot to start the plug in the hole and to handle it easily! 
Thanks,Matt

GM and NGK specifically recommends against anti-seize on the spark plugs with metal coated threads, which is the OE recommendation for our LS motors.

Also, there is heat transfer between spark plug insulator and the cylinder head to keep the spark plug at a specific operating temp ..antiseize while great for removing the plugs, reduces the heat transfer, keeping the insulator at a higher operating temp.
Just put them in clean and dry. I personally would not keep them in for 100K miles, would never happen with as much screwing around I do on my engines.

I took out the original plugs at 84 K miles.... no anti-seize on them...what a pain...
I put anti-seize on the news ones and when I took them out at 100 K miles to install AR headers, they came out easily....
Learning - use anti-seize

I want to change my plugs myself. What size of socket and how difficult are they to remove. Thinking about spraying some WD-40 in the plug area before trying to removing them. What brand do you recommend? Do you recommend changing the wires at the same time? I have about 75,000 on a 2005. What tips do have to make the job a little easier?
