Spark plug wires crossfiring ? 78 SB L-48

Hi All
I have problem that I believe is coming from cross-firing of my plug wires.
Can someone explain what wires on each bank have to be separated the most to help eliminate this condition?
Thanks in advance

Use wire spacers and don't cross the wires. Try to install them the way they came from the factory.

Thanks for your impute.
I'm still searching for which wires tend to crossfire the most commonly.

replace ignition wires that are the correct type for this application. don't use just any type of wire available. use of good wires of the proper application should not cross fire. use tyraps and plastic loom if wires go near or touch metal that could damage them. us silicone grease on the inside of the boots so that moisture will not eat away at the conductor.measure resistance of the wires make sure they are within the proper range that this engine calls for. new wires must be checked for resistance many a new wire i found defective.
