Withers cannot be hit where the other two heads are, including the "arms" connecting to the heads. The same applies to their collision box, as a Wither can fly through a one block hole upwards.
Steps to Reproduce:
1. Make a new Creative world.
2. Spawn a Wither.
3. When you try to hit the two smaller heads, notice how the Wither takes no damage.
4. Also, press F3+B to show entity collision boxes and notice the box on the Wither only includes the main head and spine.

Confirmed for 1.8.7. The hitbox should be at least a little bit bigger to accommodate the other two heads.
Would it be okay to request a review of this ticket since similar reports regarding how entity hitboxes don't correctly correspond with their models are considered issues? (MC-142848, MC-195133, MC-212565, MC-208015, MC-198242, MC-148559, MC-119372, MC-80877, etc...) It does seem rather strange that the wither's shoulder heads aren't included within their hitboxes and since similar behavior with other entities is considered to be valid problems, maybe this should be reconsidered? 🙂
