Raise the car as far off the ground as possible, like 2 feet at least. Most floor jacks can't go that high but you can do it with blocks.
remove the radiator so it doesn't get damaged. it's a good time to change hoses to a Samco kit anyway.
if you will be removing the intake manifold, do it before removal and if you're removing the head, remove that too. These things detached free up space.
Get an engine lift leveler. look that up.
if possible, get a ganrty crane for engine hoist and move the car for minor latteral adjustments.
If you can remove the driveshaft with the transmission, it will prevent oil loss.
protect or remove the headlights.
Lotz of cardboard to protect surfaces (from you, especially)
