I remember now, it was on VA68goat's engine, normally adjusted, the poly hex area contacted the rocker body. In his engine diags thread, a pic was posted of the witness mark.

I think the suspected "witness mark" was actually a wrench mark on the scorpion rockers I had at the time. I think Paul ruled that out early on. Remember it was the collapsed piston skirt that happened when the pickup tube fell off on the dyno. I still have pictures of the rockers on my other laptop. The rockers never touched the tapped the valve cover.

Go back and look at the pics, the hex on the polys were contacting the rockers, I remember moving them around and watched them contact, think it might even be on your thread. Understand it wasn't the core issue, but it was happening.

I went back and found the pictures. The guys that saw this in person and in photos thought this was a wrench mark of some sort and not a clearance issue. I doubt Paul would have missed this during assembly.

I don't disagree that the damage could be a wrench kiss. But the setscrew sticking out of the rocker arm nut looks like short pushrods to me. Or the trunnion was upside down. Either way, something was not right there.

Okay no one cares but someone one day will.

If those are die cast Crane roller rockers I would not use them on a engine I cared about.

I missed - but are the lunati rollers hydraulic or solid??

I think they were made by Scorpion. I ended up switching to Crower 1.65 rockers. Though it wasn't the source of the issue I had at the time, I think it was a good improvement for the build!
