Spark Plugs for 6.2L

[bad_idea]

I just got done changing the plugs and wires. Wasn't the worst set of plugs I've changed, but close. Driver's side I did from the top, no problem. I pulled the passenger tire and wheel liner to access from the side. Wasn't that bad, except for cylinder 8. My truck has the rear heat and a/c, so the heater lines for the rear unit run RIGHT in front of cylinder #8. It took me the longest just to pull the plug wire off of #8.
