Most definately.
You have a clearance issue with the valve retainer.
How many threads do they rocker nuts engage the stud by? It seems the locking grub screw is a long way down inside the nut.
I'd say you need possibly all of this: a different rocker arm, a lash cap, longer studs, longer pushrods. And check for clearance everywhere, including the roller contact pattern on the valve stem.
