Should spin freely. First, make sure you're not pushing against the valve springs. If you're not and it's still hard to turn, pull it apart and check for burrs, dirt, etc. Put it back together and retorque the bolts...make sure you do it in a cross pattern...

Also ensure that you have the circlip in the cam cap slot. This aligns the cam correctly with the other gears. Also if the cam is not lined up properly it will drag a little. Hope this helps.
