On my forty 216, the brass plug that screws into the oil
distributor to connect the rocker arm line has a restrictive
orfice. Is it stock or someone's idea to increase oil
pressure to the bearings?

I don't quite follow your question.The 1940 has an internal oil distributor valve.Its behind the little stamped plate that is retained by three screws.The 1939 and prior had an external valve.It was a cast iron cylinder the was bolted to the block.
If you have a 1940 or newer engine it will have the stamped plate and no holes in the plate for a fitting-but just behind the plate the block has the fitting for the rocker arm oil line.

That is the fitting that I am talking about. Coming out of the
block by the oil dist, going to the rocker assembly. The brass
plug is closed except for an orfice. It is intended to restrict
the flow of oil through the line to the rockers. Is that a
factory device?

Yes.The fitting is tapped into the main high pressure oil gallery.If the flow to the rocker arms was not restricted they would be floded with oil.This was done this way to get oil to the rocker arms instantly.On the 1937-38 they were fed from the low pressure side-1939 changed to the high pressure.
