I never really looked into detail at the radiator, but today I noticed it was some Boyosho Brand and said it was aluminum and made in Japan, is this stock???

Yes the stock radiator is aluminum. I don't know the manufacturer offhand, and in fact it may or may not be the same manufacturer for all years.
