Does anyone know why the new rod caps Do not Have oil grooves?

The rods journals get oiled through the crankshaft and that hole is pointless.
The cyclinders get oiled with what flies out of the sides of the bearing.
I could be mistaken.
Might wait for other to reply just in case.

You don't need the grooves. Those look like scat I-beam rods , make sure you get the rod bearing shells in the right location (marked upper and lower) and the rods installed with the rod chamfer toward the crank radius.
