An engine builder friend used Hughes Rockers and had valvetrain issues. Swapped over to T&D rockers and the problems went away.

The Valley machine build used in the dyno competition used Hughes rocker gear, and the motor has now also been in a car several years without any issues.
I am not a big Hughes fan, but in fairness to them, after you saying what you did, making this point is valid.
Valley performance is very, very good shop.
