This is very important when taking things apart. That cocking action on the cam can brake the end of the cam.
This is done without the plugs in place. So you will not feel any resistance as you turn the engine back and forth. The final check is done with the the tensioner in place and after cranking the engine around twice in the normal direction.
And always set the exhaust cam first then take up the cam chain slack and do the intake cam last . It is OK to carefully rotate the engine back or forth as long as you hold the tension on the cam chain with your finger.

I held the tension down on the cam chain, and turned the engine counter-clockwise a few degrees. However, this just causes the intake cam to fight against the valve pressure instead.
