...Where's the chain fastened on the forward end?
I am guessing it's fastened with an eyebolt replacing a front headbolt. I tend to use eyebolts but sometimes will fasten the chain right to the head with a headbolt. Usually I feel better about removing the rocker arm assembly so that nothing gets bent.
I have used a tow-rope or cargo-strap and just wrapped it around the engine like a sling. But this is probably not recommended.
For me a leveler is necessary, because the engine wants to rotate.
