Help with spark plug wires

I'm ready to re-install my new plug wires, but I forgot the sequence that thay go in.I have a 67 skylark 340....Can anybody help me?

Thanks,

 

I'm not sure on 340's, but alot of times the firing order will be cast on the intake manifold.

 

It wasn't on the manifold, but I got lucky, a friend of mine came up with it-

Thanks 72,

Jeff
