The Noda B'Yehuda (Tinyanah Evan HaEzer Siman 79) famously writes in regards to making a match between a bachelor that has the same name as the father of the potential bride that one need not be concerned about this. Rebbe Yehuda HaChossid in his famous will (tzavah) writes that one shouldn't make such a shidduch.
The Noda B'Yehuda writes very strongly against anyone going against what it says in the Talmud, mentioning specifically other relationships (marriage set-ups) that Rebbe Yehuda HaChossid wrote against and that the Talmud permitted or said even was a mitzvah! He writes so strongly that such a person's words shouldn't be accepted. Because of this however he writes afterwards a reason why perhaps Rebbe Yehuda HaChossid was machmir in these things.
My question is, would the Noda B'Yehuda speak or feel so strongly against other things it says in the Tzavah? For example (and specifically) not taking a haircut on Rosh Chodesh. Would we have any reason to believe that he also perhaps didn't hold of this prohibition? (Arguably, it's more difficult to believe as much, since this prohibition was already brought in poskim by the time the Noda B'Yehuda lived.) Do we have a proof to this from anywhere or a reason to think that he would also disagree with this point and others?
