Stock 340 Rocker Arm Order

I have 34LT and 35 RT rocker arms on the 340 I am rebuilding after someone else had it torn apart. I am told the notch in the rocker arm shaft goes to the front of the left head and to the rear on the right head. Does anyone know what order the rocker arms go on from front to back on each side? One side starts with a 34LT in the front and the other side starts with a 35 RT in the front. I can't find any references on line and the building a Small block manual is not clear to me. Just trying to get it right. Thank you.
