OK guys plz dont jump me if this is a repost but ive searched...

what are the differences between a NA head and a Turbo head besides the cams.... i have 2 turbo heads both are supposedly no good... havent taken them to a shop yet, just bought them any way a good turbo head is hard to find but my buddy has a remanufactured NA head he will give me if it will work
