not enough in the pictures for me to tell (maybe someone else can) but there should be good diagrams/pictures on line or in the manual....What year is this? also you should be able to reach up the exhaust and feel if the valves are aligned in the ports correctly, and of course if they move smoothly

Are you trying to move them by hand or with the engine running?
Remember that it should be in the governor and thus you may not be able to move them by hand.

😳 i hope you weren’t yawrning on it hard because you are supposed to use a special tool to lock the PV arm in place when removing that bolt Same when reinstalling.
