roller rockers

I have tried them all.
It’s interesting with the exact same peak lift my Holroyd ones are faster than my Harland-Sharp ones. Just a matter of the geometry of a stamped steel rocker vs. a roller rocker producing a different lift curve. I’ve never broken one of the Holroyd’s or Harland Sharp (knock on wood). I used to break the same punched steel ones all the time before I had Holroyd modify them for me. Only roller rockers I have ever broke were Crane on a big block Mopar. On that after changing to T&D I never had another problem.
