I 2nd that book. Very informative and it has a hipo section for tweaking. Hundreds of pictures in a clear and concise method, you really can't screw up. When I rebuilt mine I was greatly impressed by the previous rebuilder, as I have had this tranny for 25 years and haven't put it into a car yet. I bought the book and did a refresh on the internals. I didn't change any bushings but that isn't really that hard. It's a good time to strenghten your trans for later mods, that's why I went through mine, maybe one day i'll get that stroker.....
