Speedmaster Stainless Rocker Arm Issues

I mentioned that and got dissed. It's a fix.
You didn't get dissed, Mike. You don't know if clearance will be an issue until you know the shaft is at the right place. Then you can rightfully determine whether the beehive springs need to be used. I call that being informed. There was no disrespect given, at least not from me.
Haven't read all the posts.

- the rocker geometry can be correct...& still have rocker to retainer contact. More likely with the SBM because the rocker is so short.
- use beehive or conical springs! Problem solved.
Yes it can. But again, if you don't know whether the shaft is at the right place, you don't know for certain why there isn't enough clearance. If the geometry is truly correct, not just centered on the valve tip, and you still have clearance issues, by all means, use a different spring if that fixes the issue. FWIW, I haven't had to grind on a rocker for over 15 years, and I rarely run a beehive spring.

On the madhatta360 motor, I did go with a smaller spring (not beehive) because even with the geometry correct, his was one of the rare occasions that there was still a minor clearance issue. It rarely happens, yet you hear about this issue all the time and the rocker gets blamed. Fix the geometry and the odds are that you solve the clearance issue as well.
