Plug change complete!
Plug change complete! I just completed my first plug change on an LS1. I have done an LT1 twice so I sorta knew what I was getting into. I started on the pass. side, plug #8 because I knew it was going to be the hardest. Unbolted coil bracket and AIR pipe and I had that plug out in about 5 minutes after that. PIECE OF CAKE! Granted I have fairly skinny arms but #8 was very easy. Everything went smoothly from there 
All in all, it took me about a total of 1 and a half hours, taking my time. Not bad for a first time eh?
One question, who the hell puts one freaking Bosch platinum and leaves all of the rest alone? The Bosch didnt even seem to have an electrode anymore! It looked much worse than all of the rest of the AC Delcos which looked normal.
Oh, I used NGK TR-55s with suprisingly a fixed tip (not the unscrewable type)
I am still having this high RPM detonation issue though. I am not even sure it is detonation but I need to get that fixed. I didnt want to get a colder plug because of the fouling issue. I read they foul much easier. Now I kinda wish I would have used TR6s.
Thanks to everyone on this site and the search function for saving me around $500 installing my own plugs.

Congrats on your first LS1 plug change. 
Good job getting it done so quick. Arm size really does make a difference though. Even after doing multiple plug changes on LS1s, I doubt I could beat your 1.5 hour time.

Even after doing multiple plug changes on LS1s, I doubt I could beat your 1.5 hour time. i keep forgetting about the air pipe getting in the way since mine has been long gone, but i only have two coil pack bracket bolts installed so it takes absolutely no time to get them out of the way on plug changes. I can change mine in just over a half hour these days.
1.5 hrs is pretty good considering you had to fight with all the extra bolts to get the stuff out of your way

Mike-I did have a hard time getting that back coil bracket bolt off but I just used a short 10 mm wrench. I had enough space to get about 1/3 turn at a time with the 12 point side. I left that damn thing off. I may try the TR6's soon as I am still having detonation in high RPMs. I dont know if I want to change the plugs out every 5,000 miles though.
