I?s there oil coming out of the rocker shafts etc on the right bank when it is rattling The shaft gallery is connected to the lifter gallery only on the right bank with the feed coming from the left lifter gallery. Also it can take ages for the last lifters to quieten up.
I wouldn't be too worried about not being able to turn the pushrods with the engine stopped the lifters are a piston inside a sleeve with a spring under the piston to provide some static pressure when there is no oil pressure. It some cases it can be high enough to make turning the rods difficult, particularly if there is any residual oil pressure (which there will be on lifters in motion). A finger over the spark plug hole compression test will tell you if the valves are seating (if it blows your finger out they're seating - note its finger OVER the whole NOT in it!)
