I have both this book and the P/PX hayne's manual. The hayne's manual is awful. Countless things are flat our wrong, the diagrams are grainy, and there are topics missing that I've needed reference on. It's a pretty bad book.
This blue restoration book is absolutely fantastic. I can't recommend this book enough. It is incredibly thorough and covered every possible question I had doing my first rebuild. And I went into this having never worked on any engine at all. It's full color and the photos are numerous and very helpful. If you need a reference, get this book.
The only complaint I'd have about the restoration book is it's really laid out kind of chronologically. So if you need the torque spec on the clutch nut for example, you'd have to find the reassembling the clutch section. There's not really an appendix. But after having read it cover to cover 3-4 times, it really does cover everything.
