You can crank the engine in 3 easy ways that come to mind.
1- the start/stop button. Just make sure to stop it after a short cranking burst.
2- 22mm socket on the crank directly.
3- with the intake removed, use a starter button between the B+ connection and the start signal terminal of the starter. This is my preferred method. You can see the valves while you crank, and it requires no extra disassembly of the fan and other components on the front of the engine to access the crank pulley.
