This is the way I was taught ....
If you can, remove the spark plugs and pull the coil wire. Compression puts a load on the dry cylinder walls.
Run the starter for no more than about 15 sec at a time. Once you see oil pressure ... do it again. The put the plugs in, (no coil) do it again and listen for any bad noises.
If the oil pressure is good, connect the coil and see what you get.
