The engine temp ran 185+- oil pressure never below 50 psi. The plan was to run it for 20 minutes, shut it down, drain the oil and change the filter. I almost made it.

The problem may have been caused by not having enough RPM during the break in period - as others noted, I try to stay between 1500 and 2000 and move the speed around a lot. You need a lot of oil splashing on the cam to get it and the lifters broken in. If it starts to gall, things go bad very fast!
