The rocker arm stands are held down with 3/8" bolts. Using a slightly longer Grade 8 bolt to replace the front and rear rocker stand bolts, and bolting a short piece of angle iron under them gives you a very secure place to attach a chain or a load-leveler, right on center of the engine. No problems with twisting, or risking head bolt damage.
