Are these pictures of the opening side or closing side or both?
If they are of the closing side I think you need more valve spring pressure to keep the rollers on the lobe all the time, not hopping over the nose and sliding when they hit the backside of the lobes
If it is on both sides I would add more spring pressures on the seats and opened both I like 230+ lbs. on the seta sand from 600+ up opened
That is a big grind, lots of duration at .050
Do you know the spring pressures it had when you took it apart this time?
BTW, I don't like or use synthetic motor oil in any of my old motors, especially Hi Po drag race motors I like and use Valvoline VR1 10W30Wt in them now
If they made 5W20 Wt. in VR1 I would use that instead of their 10W30Wt
