I will be installing new plugs in my car soon. I am going with the TR55s and Taylor wires. Anyone know the recommended gap?

I put the TR55 (can't remember the rest of the number) Iridium plugs recently in my SS. The box specifically said not to try and change the gap because the tips are small and can break. I cheked them anyway and they were around .58.
