Piston numbering (flathead)

How are pistons numbered on 239 flatheads? 1234 on right side or odd /even like on modern engines.

Piston count

Dick, very good, you can count to eight now. I really need to know how the pistons are installed. If they are installed per the tune up specs, the numbers on the rods wont match, ie in order like a modern engine.

They aren't in numerical order along the crank on any Ford engine except a 4-banger. It doesn't matter anyway, as long as the rods are on the correct side of the engine.
