Cam shaft rotation (Stiff)

Not sure if the cams should be very difficult to turn by hand???

I'm just now getting my chains hooked up and notice the cams are not turning by hand (at least easily).

I could add a little more force and make them turn, but wanted to get some opinions on how much force (lbs) should be expected to turn the cams from the flywheel.

The pistons are turning fine (I'd say around 5 lbs force to get those to turn (with no chains hooked up)...

I've just never rotated the cams yet with the chains hooked up so I'm a bit confused.

Thanks in advance for your responses.
