It would be more intuitive to me if you approached the above proceedure from
the other direction.  Suggedstion:

remove #1 spark plug.
Insert screwdriver (this is a cheap gauge for finding approx. TDC)
Rotate the crank until piston is at top
with flashlight (friend helps too) fine tune to the tdc timing mark on flywheel.
Now rotate cam to check for interference.

The cam, having less mass, is easier to control and you will recognize the
resistance quicker.
