I personally used a long load rated eye bolt where the second to last head bolt goes and put a grade 8 bolt through a loop in the chain in an unused hole near thermostat. It worked well for me. I wrapped the chain with red rags and duct tape to protect the valve cover. I would consider an engine leveler if you can find one it would make this a one man job. I've seen them in the harbor freight catalog.
I have heard on here of guys hooking the chain directly to the valve assembly also but this scares the hell out of me personally. Or making a sling or hooking onto the intake / exhaust manifold also. there are many different ways to do this but, the way I did required not having to put on the valve cover and the least possibility of damage to the engine.
Good luck.
