Contact the manager at Pace Pontiac in Niles, Ohio and ask him if he has any suggestions. They specialize in GM Performance Parts, but I also saw books Honda, Ford, etc. at their dealership. As far as I've heard, they are the largest GM Performance Parts Dealer in at least the nation, if not the world. Just helped do an inventory and they had just about everything, including complete 350 GM Performance engines and more. Look for them on the web, they have a site with contact info. They may be able to give you some advice.
