I use two 1/2-13 bolts about 1" longer than the head bolts and use them to attach a couple of short pieces of 2" angle iron with 1" holes drilled in the upright flange. Bolt the engine lift chain(s) to the angle iron and you'll have a strong, reliable lift point. Using the head bolts to attach the chain prevents the bolts from getting a good bite on the threads in the block.
