    Alot of people here use copper autolite plugs with a s/c motor. 606's for stock, 605's for light mods, 104's for when you drop pulley sizes. I gap mine to .55. I think .60 is stock. Stock wires are fine. People mostly upgrade wires for looks and perhaps more durability if you're constantly changing plugs. Keep in mind that copper plugs need to be changed about every 10k miles or every other oil change.
