My choice would be stock GM wires (or factory replacements if yours are deteriorated) and NGK TR55 plugs.

I'd use stock gm plug wires and since you'll be cammed, I'd probably use NGK TR6's. It seems a lot of people are going from the tr55's to them now. For na, the guy that did my first build runs those in all his builds.
