Doing it cold with engine down is acceptable for initial startup and if you really know what you are doing. Then follow-up with "hot and running "after engine start.

Makes one wonder how the engine plant did it when the engine was built doesn't it?

My bet is the engine plant adjusted the valves as part of the initial assembly before the engine was altogether. Solid and hydraulic lifters both.

That said, I've always done it the way you described.

My feelings as well. I've always done it during assembly prior to initial fire up and then 'double checked it' warm and running to make sure.
When I assembled my '61's engine a month ago, I did exactly that. The 'hot and running' check I did after fire -up verified that I got them right during assembly, so I simply re-installed the valve covers and moved on. I'm always more comfortable when I KNOW none of the valves are too tight.
