Some of my favorite burs for gourd carving:
Carbide: #'s 1, 4, 8, 37, 701, and 7408
Diamond: #'s  4, FB4, FL, and WH
All of these Friction Grip Dental Burs are 1/16 inch shaft size.

Carbide burs are good for fast, agressive cutting in many surfaces.  They are inexpensive, so if they get dull it isn't a big expense to replace a bur with a new, sharp one.  They shouldn't dull too quickly on gourds, but if you are carving glass, metal or other hard surfaces they will need to be replaced frequently.  

Diamond burs are not as effective for carving through the gourd skin, but are good for sculpting, and sanding the inner gourd pulp. Diamond burs work well on hard materials such as stone, egg, glass,etc. When using diamond burs on hard surfaces, use water for lubrication to extend the life of the bit.
