Solid Roller Lifters on a Hydraulic Roller Cam?

I watched that Engine Masters episode last night. Good info. Season 4 Episode 7 (I think).
I'd like to see a follow-up on the longevity question posed.
I will be at westech Monday or Tuesday next week. If I remember I’ll ask Brule and Troy if they’ve put any more dyno laps on that engine.
How many miles/hours on them? Street driving too? Thanks!
All street driving/towing. It’s my daily driver with LOTS of miles on it.
