They look to be a machined set of Dura-Bond F26 bearings with the oiling restrictors machined into the back of the bearing surface.

The thrust bearing oiling mod consists of drilling a small (.030") hole through the #3 main bearing upper insert half and the #3 main journal into the oil feed gallery. You drill on the thrust bearing side (obviously).

Once you have this hole - the pressure feed force-lubricates the thrust surface of the crank.

The crank gets loaded whenever you push in the clutch.

It is described in the November 2012 POCA Newsletter on Page 13, in an article by some guy named Jack DeRyke. I'm not sure if this DeRyke guy is familiar with our engines or not, but it seemed like a good mod to me.

Jack drilled the hole with a long, flexible aircraft bit, but I was able to do mine with a small, battery powered dremmel pistol type deal.

Good Luck -
