How to neatly set spark plug wires on M103 engine?

I had to redo a job today - reinstall the "upper cover" - the plate that covers the upper part of  timing chain where the distributor mounts - I had apparently crimpt the u-shapped rubber gasket that fits on the bottom - that let oil (my slipperly Mobil 1 ;-) ) - seep though. 

Anyway in all the years I have had this car I could not figure out how neatly arrange the plug wires on the plastic clamshell enclosure - it's like hearding cats.

When I try to lay them flat - in a row - on the valve cover they are always moving around...

Anyone have an easy way?

I have always managed to cram the wires into the clamshell enclosure but it is always ready to burst apart

Have a nice Easter / Passover everyone....
