ok i got a 1990 civic std and i was wondering if it has a 8 or 16 valve head i should just take off the valve cover but i thought id ask you guys first it says it has a 16 valve head but i was told that was the valve cover that they used for this car just let me know cause i am going to do a homemade turbo setup on it and am wondering if i am going to have to swap heads first
