Mr 914,
Get a set of ear plugs and 2 containers for the oil dribble. Install the tensioners and place the containers to catch the dribble. Small from the drivers side, negligible from pass side. Spin up the engine with the coil grounded to get oil pressure up. Connect the coil and start the engine while observing the tensioners. Note that the spring in the tensioner should be stiff enough to keep the plunger extended such that you cannot depress it by hand. Oil pressure adds to the force on the plunger but it's real job is to dampen the movement of the plunger, that is to hold it steady.
Get the help to vary the speed of the engine and watch the action at the tensioners. If they all are tight especially when you drop speed suddenly on the engine, you are fine. If the sprocket is not hard tight against the chains you need new tensioners.
Ask me how I know all this. Ah, got a couple of used tensioners in the garage. The new ones I installed were just as good as the couple I replaced.
