Hello, I made a big mistake I bought a new set of ACDelco Spark Plugs P/N: 506C GM# 12043764. I took a picture of the wires when they were connected a while back when I was painting the engine. In the new wire set 4 of the wires are the same length and the other two are almost the same length. Below is the only unique identifier on each plug

2 Wires say D.E.E.D 8
2 Wires say D.E.E.D 7
1 Wire says D.E.E.D 1
1 Wire says D.E.E.D 4

In what order do they go installed?

When faced with these types of problems, My guess would be in the order that fits best...

Does the order matter?

good advice, CASO

And, when I asked this question several decades ago, the replies were an ah-duh moment for me.

Yes

1-5-3-6-2-4

With #1 being the lead on the cap that the rotor points to when you have the #1 cylinder at/near Top Dead Center.

Tim, I don't think that is what he meant. I believe he was referring to the markings on the plug wires as the order. Correct me if I'm wrong mauricioaglr.

Also I would cut the wires to the best suitable length and re-attach the plug ends as in a universal set so they would look proper. The hell with what it says on the wire.

I'd find the number one cylinder lead and, in proper rotation/order (given above) choose the best lengths for each cylinder/plug. Or, for a tighter fit, I'd do as Dave suggests.
