There was a henka. So what? Chiyotaikai proved that henka is only a winning move when the rikishi isn't prepared to react to that legal move. I don't even think the yokozuna got an advantage from his henka. Really, it's not like he pulled hair. :-P
If it's the bout in 1970 Aki basho, it's available on the DVD "Ozumo in the 20th Century." I haven't seen it, mind you, just read about it.
(At last, something I can comment on without sounding like a total git.)
