Another lifter noise question

Yes, when lifters are bled down, they will compress easily. It sounds like something is allowing the lifters to bleed down. They should not. Did you get the cam and lifters from the same place? Same brand? I ask for two reasons. Mopar Performance had a bad run of lifters a while back. Some may still be out there. Also, some big block lifters have oil grooves in a different spot than small block lifters. I've heard tell of a few sets that got included with a small block cam. They will act just as you describe.
