The 2V 4.6L V8 usually don't have any issues with spark plugs. It is normally the 3V engines.

 

I was going to ask if he was drunk, but he answered that...

 

oops, my bad

 

when I knocked out mine, it wasn't too bad. as lost said, #'s 4,6,7 can be a PITA if you're not careful. other than that, get you a small air compressor and blow out each individual spark plug cavity to ensure no debris gets into the combustion chamber. also if you can, since you are replacing the COP's, then get the new boots as well. Not sure if you were planning that.

As for removing the hood, nah...I didn't bother with it. The intake snorkel and cold air box came out for some wiggle room for me. I also seem to remember having trouble with the power steering reservoir...but not sure.

AS was stated though...these 2V engines don't have the bigger issues that the 3V have...no cam phasers, no broken plugs.
