What do you have for spring pressures? Are the bearings aligned properly
with the oil feeds? Are you getting oil to the bearings? What are you
using for assembly lube?

Thanks Steve, Rockers are not on yet, bearings are aligned using assembly lube. rotated easily for maybe one revolution by hand and the cam froze in the bushings--take off retaining thrust plate and cam is still frozen. second time to remove cam with sliding hammer.

Did both cams lock up at the same bearing or does it look like they were
in different spots? If the same journal then you may have an issue with
the cam bore.
Was this a running engine prior to the build or is this a new block
you're working with?

I have had to scrape in cam bearings at least once that I know of.
