If they fall back down when you barely touch them, well then I wouldn't be too confident in the trays holding them up. If it takes a fair amount of pressure, you should be ok. If you already have one magnet (most folks do), you can actually pull the lifters up into the trays a little further than what the cam lobes will, locking them a little harder into the trays. Just pull them up until the magnet breaks free from the lifter. Of course if the trays still seem like they don't want to securely hold the lifters I would find another method.
