plugs for headers

Just a question, when installing headers, cold air kit, pulley etc, what plugs are people using? hotter? colder? same?
Normally I would have said colder, but what are people on here using?

I was just looking a Lingefelter's 700+ hp kit and there is no mention of a plug change.

Yup. This seems to be the most common for LS-motors. They aren't iridium-tipped, like OEMs, nor are they platinum, which means you have to change them somewhat regularly (what - 30K-miles?...), but you'll be less prone to detonation because they're cooler to run. They're pretty inexpensive, too

Are they? I would say they're cheap.
