The Good, the Bad and the Ugly : About time

About time

I've been trying to acquire the Blu-ray in its 2014 re-mastered form but also at its fully extended length which is c.177mins. I have the 2009 re-mastering which is very poor and even at its advertised 'extended' length is only 155mins. Does anyone know of the existence of such an issue; I have a multi-region player so that is not a problem.
Just for the record: it's in my top ten of all time movie list and it keeps moving closer to the top as time goes by.
