I use GUNK, that's what its designed for. If the engine runs get the block just warm enough to be warm but not so hot you can't rest your hand on it. This will help loosen the grime.

I use a pressure washer with a fan nozzle to rinse it.

On all my other vehicles I pressure wash the engine compartment thoroughly every time I change the oil, then blow it out with an air hose and take a drive. This keeps it pretty clean.
