    Did you make sure you left nothing in any of the cylinders? Don't take offense, it's been done before. Just start loosening head bolts and see if it frees up.
    Did you verify the crank had standard journals and the bearings were standard? Just a few ideas

    C Model has the cam in the block doesnt it? Did you even have the front cover off? Will the engine turn backwards or is it locked in one spot? So all valves are closed right now and you have no rockers installed? Make sure trans isnt in gear as well as checking for timing pin still in the flywheel housing. What are you turning it with? Cat turning tool or just a breaker bar and socket on the front dampner?
