I used Cliff's book, and it was easy to follow, great information and pics. On top of that, I was able to call Cliff and talk to him many times for suggestions and recommendations. It might be worth picking that book up too if you don't already have it...
Cliff is also frequently at V8Buick.com, he has answered several of my questions on the forum.
