"How to Rebuild Big-Block Chevy Engines" by Tom Wilson. Excellent book for $12.00 and change. Search for it on Amazon. This book has most of the basic details you need to know, including torque settings and casting numbers for most of the big blocks out there. However, it doesn't deal much with aftermarket parts. It's a good primier, though.

If you're replacing bolts on your engine, about all you need to replace are the head, main bearing and rod bolts. The rocker studs are a good idea also. Those are the high stress locations. You can use the stockers for the rest. Oh, and you don't have to buy new rods, depending on what comes in the engine. If they're good rods, a shop can recondition them for you. Don't throw them out without checking. Same with the crank.
