Yes it's a hydraulic roller.
The machine shop helped with setting it up for a 9.8 SCR. I did the head cc at 62 cc, and he verified. I don't recall the other details.
Thanks for that clarification wyrmrider, I wasn't sure how to determine how it was ground.
I'll be in touch with Ken. Must have been a crazy day at the shop. Maybe Covid 19 related :(
I suppose I could change to anything now.
