slight tapping under valve covers..

hi all

is it normal, to hear sometimes a slight tapping under the valve covers?

cam is 234/238, hyd.roller, if that does matter...

rocker arms are comp pro magnum full roller

you will have to listen real closely to hear it...
..and its hearable just at idle, at higher rpms no more..

with closed hood no hearable noises...

thank you
