5.9 Magnum valve train sound

well i went for a good drive in it and they quieted down a bit but it sounds like atleast one is clapping away. I'm going to have to check them out again and triple check the torque on them. If not i'm going to be pissed if the new lifters are ****. Every magnum i've had is pretty quiet and very minimal noise from the valve train unless you over rev them and float the valves.
