you still need to basically cover the surfaces inside and outside the engine with clean fresh oil/grease, back off the valves (rockers) to release the pressure and FILL the sump with a few extra qts of oil to keep the bearings submerged,cover every part to prevent moisture from reaching the engine AFTER draining all the coolant from the block and making sure the coolant passages are dry (trash bags duct tape and plastic wrap at a minimum) a larger air tight box if you can find one over that helps
