Rocker Arm Retainers

The holes in the stamped steel retainers that are used to secure the rocker arms are offset so that there is a "short" side and a "long" side. Which way should I orient the long and the short side when installing them on a 1984 LA 360? The manual show where to locate the long and the short retainer, but not which way to orient the long and the short side.Thanks.
