They aren't required, but if you decide to route the wires over the valve covers you'll need a cut to fit universal wire kit. Otherwise normal LT1 wires will work fine in the stock locations, just make sure none of them are touching the headers.

 

As long as your route the wires through their stock location you will have no problems burning wires.
