ok... I'm just going to give you fair warning... it's a royal pain in the a$$.
I had to remove my covers to replace the gaskets (which is around 100.00 if memory serves me) from when I blew a spark plug out of the head. It's also not very easy to install.
just a list of some things I remember off the top of my head that have to be done to do this:
remove the hood
remove the cowl
remove the wiper assembly
remove the intake tube
remove the battery
remove/move alot of misc vacuume lines
remove IMRC bracket
remove/move the fuse box
remove/move the coolant tank out of the way
cut the tape hodling the wiring harness for the injectors so you can move them
lots of misc harnesses/clips laying on top on the engine
and it would probably help ALOT if you removed the brake booster assembly as that AND the lines get in the way of removing and installing the valve cover.
oh, the oil dipstick also gets in the way too... you'll want to find a way to either hold it back with something or have an extra set of hands to help ya while removing/installing it.
Someone here (I think) told me that if you jack up the engine to get it to twist that it makes this process a little easier.
good luck... I was wanting to do the same thing when I had mine off... but after removing it, I knew it wasnt going back on without getting all scratched up... so I didn't bother
