http://www.hotrodsforsale.com/hrfs/t..._big_block.htm Couldn't find a diagram for you but as I recall you can tighten up all bolts to about 40 or 45 ft.lbs. then go around proper torque sequence (center outwards) then re-torque at 60ft.lbs., then do it again at 80 ft.lbs. A torque wrench that you can set the torque and it clicks when you get to the setting works best if you have one!
