The Zetec doesn't have a a dowel or anything to set the cams in place from the factory. So they all came a little different(+ or - a few degrees). Thats why you have to get them tuned on a dyno in order to know your gains. So one guys settings would be completely different than the next guys settings. It's not like the civics were you can set your gears based on your mods.
And in order to take your cam gears off you hvae to bascially remove your cams. I mean you'll be like two steps away from taking the cams out so you mine as well get some better cams. I had the FR stage 3 and the Crowers stage 2 and they both pulled very nice. The FR3's pulled harder in the low end but the crowers pulled all the way to 8100 were I shifted.
Either way cam gears take about 30 min to swap out with or without cams. Very easy job. get a better mechaninc.
