i forgot to say, angle plug heads [RPM's and others] can require different combinations than straight plug heads.
it all hinges on what you are going to use for headers. get them first before even thinking about plug wires.
you may even consider buying a roll of plug wire and a bunch of different ends, then making a custom set of wires. it's not all that hard to do, but it can be a little more expensive. if i can do it, "a caveman can"............
