Funny, a few of us had been discussing that there are very few 429/460 rebuild books out there, and we were entertaining the idea of putting something together. One of us would handle the head porting section, the other the oiling mod section, etc. But as of just a few months ago, Kaase started wroking hard on a 460 Performance book.
In the meanwhile, if it's just no brainer assembly you need assistance with, go out and buy "How to Rebuild Your Big Block Ford," By Tom Monroe. I don't remember the exact title, but the author is definitely Tom Monroe.
Be aware that this book does not have correct casting numbers and other dimensional info such as combustion chamber volumes, etc. Those lists and tables are filled with inaccuracies, and is very much incorrect...but as far as step-by-step assembly of a regular Ford, it will get the job done.
Sorry I can't offer a better book, not much out there. There are some other books; investigate yourself.

PS: KB's valve relief is for the intake valve; passenger side cylinder bank gets the brow toward the front of the block and the driver's side cylinder bank gets the brow toward the rear of the block.
