I have recently pulled and EA81 complete, I used Nylon rock climbing strap about 1.5 - 2" wide. I would suggest using something like a tiedown strap from home depot, no need for a chain.
I would take the strap and pass it under one of the heads then cross over to the other side of the engine and pass under the other head. Then tie loops on both ends and use a carabiner to hook them together. Then hook the plance on top where the strap crosses eachother onto the hook of the hoist.
This way the load will be balanced and you will not have to worry about it tilting one way or the other.
