still soak the cylinders? then try breaking them free?

or do you think I should continue soaking the cylinders with the head on by pouring diesel into the spark plug holes and wait? and avoid taking the head off all together?

If the pistons are frozen then the chances are good that the valve train is too. You'd best remove the head, inspect it and the valves for damage/pitting, then soak the cylinders until you can hand-crank the engine. Don't overdo the force in hand cranking as you'll risk damaging stuck valves as well. Once everything is moving, you can have a good look at the cylinder walls and decide at that point whether it might be better pulling the engine and sending it out for a rebuild... which may well be what's needed; if there's damage in the upper end, it's most likely the crank needs inspecting/grinding/new bearings as well. Better to do it now while you're in rebuild-mode!
