    Emissions legal for the street

    I dont know if this question is in the right section but I was wondering how many of you all choose engine packages (IE: head & cam) that would be emissions legal? I drive my car everyday so It needs to be able to pass and some of you only put on under 5,000 miles a year. What do I need to know to pick the right head and cam combo so I can pass emissions?

    heads usually are, but cam depends on durations and lsa.

    any cam generally above a 224/224 is going to be a problem passing emissions if you have a sniffer test in youre state.
