Won't be a book that will tell you where to set initial ignition timing with those internal engine changes.
Set it with a vacuum gauge. Advance it, readjusting idle to your desired rpm until it gets to highest point, then back off timing 1", lock it down, reset rpm and see where it lands on the balancer. Adjust the idle mix screws and you should be really close.
After you are done, make sure it starts ok when warm, no starter kickback or really labored on starter. If it does, you need to retard the timing a bit until it does start OK.
