Ok, so i get to the last plug that im changing, #1 and i finally get the biach to slip in. I then procede to tighten it with the plug adapter and a wrench. I get it tight, but now i cant get the stupid plug adapter off the damn plug.

Any ideas of how to get the bastard off? I have MAC headers if that helps any. I took the alternator off too.

 

Nope. #1 is like the easiest plug to change out. Can't see what it has to do with the alternator, unless you might be referring to #2.
