I agree you may not want to change that unless its way too much neck tilt. From time to time the eyes change the relationship to the incline plane on the downswing due to the neck movements.
If this is the case it can delay if not hinder shoulder movements. This in turn leads to a steer effect.
Best way to work on this is get a stick on the ground and cast your shadow so you can fully see it.
Or hit ball with eyes closed. It cancels out the need to look at the ball so you can focus on the neck and head.
Make sure you start out small and slow so you can feel what your doing.


A side note : the best things ever for this was the EYE line glasses for putting. If you did it wrong you could not see the ball when you made a swing.
