Priobe ... those look Dove rockers ??? I had the same problem on my 427 Galaxie and found that the lip on the cup of the pushrod was contacting the rocker itself and on several , also the edge of the cup at full lift ( look for a shiny spot on the bottom of the rocker ) . In my case , it was caused by not having enough of the adjuster sticking out of the rocker ..... shortened up the pushrods and solved the problem . In looking at the photos , looks like you have about the same amount of thread on the adjuster sticking out above the nut as I did . Check all the pushrod cup lips also for signs of any contact with the adjuster . I also had a pushrod cup break off part of the cup .
Also possible you had a defective rocker , but I`m leaning towards contact somewhere .
