I may have answered my own questions, or maybe not:

Tom Wilson in his rebuild book says that if you can't find the forge
marks, orient the rod with the tangs of the bearings down.  If that's
right, then on both engines I'm rebuilding half the rods were oriented
the wrong way.  In my notes to myself I noted that on both engines, if I
was standing looking at the fan end of the crank with the rods all
pointing to my right, I could see all the rod cap numbers.  But when you
splay out the rods as if they were in the engine, half the tangs are up
and half are down.

Any thoughts?

Accoring to Wilson's book the peening method was not used in the Vanagon
engines.
