The BBM head is a medium riser head, if I remember correctly, and has very good flow numbers right out of the box. Ported it is even better. Most significantly if they are available, you will find them to be a high quality piece that will serve you well for a long time.
If you have not yet, check out their FE Cylinder Head page, click here => BBM FE Cylinder Heads. there is a lot to like about the heads including a more modern combustion chamber shape for better combustion.
Here is a pic of the chamber side of the head,
