Failed Rocker Arm

There should be a way to accurately measure IH with everything mounted... sure others have done it a bazillion times.
'Cause, when you really are near or at coil bind the next rocker will fail soon. So better try to verify that IH or your springs.

My only real concern is if for some reason another rocker goes and I'm not so lucky with the outcome.
No need to worry then. As Nm9 said in post 5.
