I use a heavy nylon strap (read 'old dog leash')
I tie one end to the #6 exhaust runner, and pull tight attaching the other end to the #2 exhaust runner. This balances the engine and transmission perfectly and allowed me to pull by myself, one hand tilting the motor the other working the hoist. Only works if you have the manifolds attached. I should have shot a pic, It was beautiful
If the head has 3 lifting holes (like later heads), use the middle and rear hole for the short chain and lift from the middle of that chain. Should balance about the same as my first suggestion.
