Yes, all good points. Don't forget to plug the oil fill, pcv openings on each valve cover, oil dip stick hole or leave the stick in and watch the amount of pressure used on the top of the manifold where the wires for the gauges lay etc. you don't want to rip them off or apart with excess pressure. I use good duct tape on VERY DRY parts so it sticks well. That idea about the butter bowl top is very good. Don't get carried away with the water near the alternator either. I think you biggest problem would be pressure, not moisture because if you watch the pressure as I mentioned above you can always remove the tape and block offs and manually dry everything immediately after cleaning. good luck!!!
