Did you clean the piston grooves well? New rings shouldnt be too hard to turn over---just how hard IS hard? You should be able to turn it by hand with a wrench on the front nut

Do you have the plugs in it?
Also one thing I have seen was when the top ring gets worn it is rounded over at the top because of the ridge at the top of the bore. Now you just put fresh square rings in the bore and that top corner will bind against the ridge. This is why I will just have an engine bored if there is a hint of a ridge. One more aspect of a re-ring is when there is a big ridge you get a lot of bore taper, this will leave a wedge shaped open space between the bore and the face of the ring but this is more of a sealing issue than a friction/drag issue.
If I ever have a engine that is burning oil through the rings AND has a big ridge AND I can not afford new pistons the best option in my opinion is to pull the pistons and carefully remove the rings clean every thing with a strong solvent like carb dip, then re install the old rings after very thouroly cleaning them and make sure they are in the same bore and faceing the same direction. Cleaning them will free them up where they can push on the bore easier and allow them to push on the bore again, also removeing them stretches them a tad and allows them to once again push on the bore. Again this is only a stop gap way of temporairly fixing an engine, the only real way to fix an engine this bad is with boreing and new pistons.

Is all the valve train on?? If you have the heads on and no lifters,pushrods and rockers on it WILL turn very hard and or slow if almost not at all. EDIT: I see you said the plugs were not in yet, so what I said dosen't matter.

It takes about 50-55 ft lbs of torque to turn the engine over. The cylinders probably have next to no oil on them so that could be part of the reason but still I didnt think itd be that hard.
That is going to be about right for a fresh engine.
