Burnt up rockers on sbc

Fresh built engine, right around 100 miles on it. Started noticing a slight valve train noise. Pulled cover to inspect/adjust the hydro lifters. Noticed pretty much every rocker is fried. Obviously lack of oil and got hot.

They are the comp roller tips.

Beehive 372lbs spring pressure and xr264hr-10 comp cam.

This was my first full engine over haul. I did the short block 4 years ago and just spent this summer finishing it. Block was sent to machine shop for cleaning and cam bearing install.

Summit racing brand roller hydro lifters

Having a tough time trying to figure out what I have causing this issue. Rear cam bearing? Lifters? Something else...? Engine has real good oil pressure, 60idle cold 30 idle hot. Pumps to 50psi with my drill and primer tool.
