It's not hard but it's time consuming if you've not tried it before. I'd read up on it first. If you don't have access to a factory manual go with a Chilton. It's the lesser of 2 evils VS Haynes.
I started to a while back on my 94, then came to my senses and paid a friend mechanic to do it. Why? Cause I'm one of those that has left over stuff in my hand when I'm done! LOL
If you do decide to dive in go with Fel Pros High end set. It comes with upgraded gaskets including the valve cover set.
