Big Block assembly manual/book or reference.

Andy and Don's books are very valuable , as well as FSM . Additionally , I recommend : clean , clean , clean and don't take ANYONE'S word about fit and tolerances . I had the machinist from hell and he messed up my rods and pistons . check and double check EVERYTHING .
I will be very thorough, first step is to clean threads and make sure all passages are good. Then slowly and diligently assemble. No hurry at all. FSM=Factory service Manual? I have that also.
