depends what you want to do...thats a really open ended question.
Are you going to stay Non-Vtec or do an LS/Vtec set up. If the latter is your choice, I refer you to the search button on this forum, the one at Honda Tech, and Google. This is a worn out topic.
And it's "use". "yous" implies a some vernacular contraction of "you all" in the informal tone.
At least its not "gangta talk" though.
