The Z6 head is out of the car, just had it cleaned/decked and put new valve stem seals in it. When I bolt down the cam caps and the rocker assembly it is extremely hard to turn the cam by the gear, even wedging a screwdriver in a hole and prying it is so hard to turn. Should it really be this hard? I torqued all the caps to spec. I know I have to work against the valve springs to turn the cam, but I didn't think it would be this hard.

just did my valve lash.. yeah its hard to turn but mine was connected to timing belt and all and i didnt pull spark plugs so of course mine was hard to turn over...why didnt u just use a socket on the cam gear?
they are pretty stiff. if you put the head together right then you'll be fine. i'd put the head on with the can caps loose though. then torque them after it's on.
It's very hard with your bare hands, with a ratchet is possible and should be hard to turn.
Note. Don;t get fancy turning it if wasn not lubed on the installation.

its because there are sixteen valves on a single camshaft that all need to be moved. It should be very hard to turn, if it isnt then you have a big issue.
