ok i know you have to install the colder plugs when you get stage 2 and the 2.8 pulley put on but how do you gap them or do they already come with the gap because i know nothing about this gapping issue because i heard some people say .40 or .35 what is the deal with this any info would be great thanks.

they dont come pre gapped, and all you need is a spark plug gap tool, you can buy them at autozones for 99 cents. very easy.
