Your spec sheet showed seat pressure, but what did it have over the nose? That looks like not enough spring load. The needles didn't seize. They flat spotted the pin and then the roller didn't roll.
I think Mike told me 620? If that makes sense? I need to find out what lifters they are. Looks like comp supplied the springs with the cam and I would assume the lifters. Majority of the lobes have wear, but some lifters are still in decent shape.
