Which Book?

Just wondering what book I should purchase for tearing down and rebuilding a 340. I'm talking beginner stuff, "Motor rebuilding for Dummies" would be the sort of thing I am looking for. I need to know what to look for when inspecting, tools required and the likes. I do have friends with the knowledge but it is time I learn more so I can take it as far as I can. I have shop manuals but I need something that will take me right from the very basics through a total rebuild.
I am not totally in the dark but do not have the confidence in what I know and don't want to screw things up.
Thanks.
