Maybe moving the subject to the street section might conjure up additional information and examples.
That said, this one within that thread I linked was an eye opener.....

"Yup, monitor lash, look closer at lifters if you see a 'decay' of adjustment. Considering the length of time, checking seat psi is a good idea too. I've run a number of SRs on the street without issues. The one engine went 225,000 miles."

As noted I worked with Tim at Bullet Racing Cams when I changed to my current solid roller set up. I did so for a less aggressive lobe profile and to reduce spring pressure.
