Pistons and rods going in...Need help fast!!!

Starting to put pistons and rods in and I have a vital question regarding the orientation of the rods.

I have noticed that the two side surfaces down on the big end are different, one side has more thrust area tha the other. Obviously ether the two larger surfaces or the two smaller surfaces of the two rods face each other.

I had things like this well marked on my OEM rods but I dont have them here in the garage. The rods I have now are the Scat forged.

Can someone steer me in the right direction on what surfaces of the rods face each other.

Here is a photo of my #1 rod installed, is this right or wrong?

That one is correct.
The large chamfer on the rod goes towards the crank journal radius. The bearing tabs go towards the pan rail as well.
