Spark Plug wires

[dochummer]

For the Summit Plug wires, is only one set necessary? I'm guessing from the picture that that is the case. In addition, will I need additional insulation sleeves or are these fine as they are? I just want to make sure that I get the right stuff to minimize headaches...

This is what I'm planning to purchase from Summit Racing:

1x SUM-887830 Summit Spark Plug wires $54.95
8x ACF-41-985 AC Delco Iridium Spark Plugs $5.95 each (i believe these are gapped at .040?)
1x LCT-37534 Loctite Dielectric grease $2.95
1x LCT-37616 Anti-Seize Stick $3.95

My understanding is the MSD-32829 wires are a little long and would require additional insultation. And, the ACDelco wires cost about 3x's as much...?
