Ken talks about growing chest for about a year before really starting to work on head voice. He starts his explanation of how to do this and how it works at 27:34.
Do remember, that whilst you are stretching your chest voice, you also do bridging exercises. The 'powerful' head voice training comes after training those 2 components for a long time.
