Above is correct, i also have a 96 z28 and im assuming your puttin a hot cam kit in it like i did 2 months ago, if your not, you better, and it is well worth it! i got about 65hp out of it, well combined with a 52mm throttle. Use the book, you can order chilton for cheap on ebay, but only try if you know what your doing, and ALWAYS use correct torque, dont hand tighten stuff like a few of my sloppy friends do
