I bar the engine around while doing a leak down.

Pull all the plugs, plug the tester into a hole which will likely push the piston down the bore if the valves are closed. Quickly rotate the engine around with a long bar until the valves close and pressure starts to increase. Continue to try to rotate the engine against the pressure until you can't go any further. Give it a few seconds to normalize and take a reading.

Consistent from hole to hole. Doesn't require any disassembly beyond pulling the plugs. Been doing it like this for years.
