Headers to 2.5" Ramhorns

[Green Monster]

Are the spark plug wires routed around the sides and under the manifolds? My plug wire retainers are gone so I could use some direction on where these wires should be routed and what retainers should be used to work with ram horn manifolds. The attached photo seems to show two small spark plug retainers.

Where would these go? I presume these go somewhere halfway on each side since they hold only two wires each.
