rod orientation?

I apologize if this isn't advanced enough for advanced tech, but I couldn't find info anywhere else. I bought some eagle forged 5.7" h-beam rods, and one of my friends told me that it's possible to install them backwards because of the location of the oil passages. Is this true? If so, what's the proper way to install them? any help would be great, thanks.

If you look at the bearing part of the rod you'll see a chamfer on one side. The chamfer goes against the fillet on the crank (curved radius). The side without the chamfer goes against the other con rod on the same journal.

You'll know if you have it wrong when you install and torque the bottom end.

The rotating assembly will lock if the chamfer and fillet are not mated.

It's always a good idea to spin the crankshaft after doing the torque sequence on each rod, cap, etc.

The mantra I recite when assembling pistons on rod is - tang to the dome, tang to the dome, tang to the dome....

the bearing tang on the rod is on the same side as the dome on the piston ( which is the exhaust side if you dont have a dome)
