small block oil priming question

Technically, doesn't it go in 2 ways ?
(The right way, and 180 degrees of)

The reason I mention this is, if it truly only goes in one way, then "in is good"

The gear will go in the same number of ways as the number of teeth on the gear. To get the slot aimed at the #1 cylinder, it can go in two ways and still be correct.
