Its all down to preference.
If your rocker arm is going to go, and rocker arms stoppers (RAS) are present, what happnes then? Will it mess anything else up in the engine?...
Would you rather a rocker arm going, or something worse?...

Hard to know...




On RB engines they are not needed as they have a different rocker arm set up.
RB Engines dont need them as its a different setup....
