What are your cam specs? Maybe not enough spring pressure? Spring surge/harmonics can tear up stuff sometimes as bad as too much pressure especially with some of these aggressive lobe profiles.

Cam is the Mopar 296/557 Purple Shaft. Spring pressure is slightly high for the application. Valve train geometry was spot on but coil bind was not ideal. At full lift there was still miles of clearance before coil bind.
I would say about half of the valves appear to have rotated which I had not seen in the past.
I had run 1.5 C.A.T. rockers previously with no issues other than replacing the junk roller bearings years back. I installed these 1.6 C.A.T's just before Drag Weekend though. They were still new in the box prior to this trip. Lash was confirmed several times prior to closing up the motor.
The adjusters are still tight and at first glance I see no bent push rods.
