Use the search function - I tried "spark plug wire" and "spark plug lead" and limited to the search to topics only, and got a single page of hits for each of the items. I think that will give you a good start on the wire question.
For the judging part, the most obvious item I look at, as a first glance - is the lead for the number one cylinder an angled or straight connector? For the Pagoda it should be straight. Should also be black, oops, the wires should be black.
The various threads will give you the technical details, which are the most important to be correct - the type of wire and the resistance of the connector.
There is also further information in the Technical Manual:
