Derrick,
If I remember they were only 2" high, not much different and they cleared with no problem. My hood had the factory modification where the cross bracing was cut away for air cleaner clearance.I went to my local speed shop and with the base diameter and the lowest profile which was 1 3/4" or 2" they were perfect. The top is called the K&N X-Stream top, all can be purchased seperatly.
