The cheapest test: Remove valve cover. Remove rocker assembly. Remove push rods (make holes in board and install in order front to rear the push rods. Never,never pound on push rods). Apply Kroil oil or other penetrating on valves and springs and down the push rod holes. Very lightly tap the end of the valves with soft instrument. You will be able to tell if the valves are free by sound and feel. With spark plugs removed try to turn the engine by hand if the valves are all free and level. No piston damage can occur as all valves should be up. This should free the lifters if they are down. Reinstall the push rods and rocker assembly, with set screws in full up position. Then set valve lash. As you do this you will apply a steady down pressure on lifters. If a lifter is stuck up it will be apparent. Total cost=cover gasket. Total time about forty five minutes.
