<VV> Noisy Valves

The "deep dimple" lifters came from "The Source" in 2007. I do not know the brand. The other thing I forgot to mention was that the heads have after market high performance valve springs.I assume this means the springs have a higher rate.Could this cause the lifters to collapse a bit more than normal and not return to zero lash before the next lifting cycle? The engine runs great but the tapping is annoying.
The tapping stops when I adjust while running, but after a few seconds it returns. Unfortunately, it is several valves.
Thank you,

 Now that sounds like worn valve guides.....and yes the performance springs are stiffer..not softer
