Most LS engines have a lifting bracket on the left rear head (intended, I believe, for a special clamp). I drilled the bracket to be able to bolt a chain to it. This worked well when I first installed the engine completely dressed. Later I learned it is much easier to bolt a leveling bar to each head with the engine naked...ie no intake manifold, coil packs, or accessories.

FWIW, the front or primary O2 sensors are necessary as they fine tune the air/fuel mixture. The rear or secondary O2 sensors have no affect on the air/fuel ratio and cannot control anything. Their only purpose is to monitor the efficiency of the catalytic converters.
