I would like to upgrade to 8.5 mm MSD plug wires. Do I need to buy better spark plugs as well or are will the ones that I have be good enough? Also, since my car as high mileage, will upgrading the wires or plugs be hard on the engine?

Don't need to upgrade plugs with the wires, but AC Delco Iridium plugs are AWESOME.
