It sounds like Tush has you all filled in! I'll confirm, as I have my engine sitting on the stand right now using 5/16-18 bolts that are 1/2" longer than the mount extensions with washers...So in your case 3 bolts that are 1-5/8" long. The 4th bolt can be 2" long, and will need a nut since it goes through the starter bolt hole, which is not tapped, but is a through hole. I plan to brace the front of the engine for storage, as I even have the generator mounted to it.
For lifting, do not be tempted to use the head studs, and do not even allow the chains to contact them during the lift, as you WILL crack the block if you do. There are several decent places to bolt a chain to the engine. Be sure to tighten the chain right up against the block, or the bolts will bend and it will increase the chance of cracking the block. Tighten the chain right down. Some possibilities... Bell housing mounting holes, front plate or it's mounting holes.
If you use a strap, you will need some way to prevent it from sliding. I've never been a strap lifter, myself, since I have had several friends drop pricey parts when the straps slid off.
