[Orange Blaze]

Raceland 56 Washington County 7
Bethlehem 19 Washington County 14

Using these scores as a reference point I would flip Raceland and Bethlehem in the rankings.

So in 4A #1 JC beats Harlan 33-2 and #8 Wayne County beats Harlan 42-0. Should 4A flip those two teams?

In your example it is two teams that blew out a common opponent.  In mine it was one team blowing out a team that a higher ranked team  barely beat.  Not the same thing.
