i heared that because aem cam gears only have 3 bolts that arn’t as good as crower or any of the other brands that have 4 or 5 (if they even mad ones with 5)…i just got a whole new crower valve train and i am looking for some gears…aem seem to be the cheapest in price and i was wondering if i should purchase them or not…from the way it looks it seems like a lot of people are using them and that their havn’t been any complaints…will you guys inform me? and yes i already did a search…
thanx,
Dan 
i have ben using them for about 2 years now. i dont have any complaints.
