Okay, I realize that on my LS1 the wires are simply coil to plug, coil to plug and they are very short. My question is just how hard is it to change them yourself?

I have good general mechanical skills and long arms and skinny fingers. ...however it looks like some of those wires on the rear cylinders are pretty hidden. Can I do it myself?

 

i have not pulled the wires myself, but i have bee reading about header installs (i want to install some myself) and the guys have been saying the the back ones take some patience. to remove turn the end on the coil pack side to side while pulling and it will come off then twist the plug side while pulling. one guy said it took him almost ten minutes to remove one of the rear ones. i think you can do this as well as anyone else.
