The cam towers are line bored at the factory after they are installed on the
head. When you have the head milled you have to mill both sides to make sure
the tower pads are still in the same plane.If you have new towers you may
need to get them re bored or do some careful shimming to get them in line. The
answer to the question is that you should be able to turn the cam without the
followers in place. To install the cam towers put the cam through them and
tighten just a little at a time, turning the cam as you go. If it binds up you
are bending the cam and it will break sooner or later.

Just had my valves done and cam and rockers ground. When I mount the cam in
the cam towers and tighten caps, should you be able to turn cam by hand with
everything tightened? I for get the rule there. The cam towers and cam are
being put on a newly aquired head that has just been to the shop.
Thanks in advanced!
