Kashrut Laws Don't Apply To Noachides

I saw in one Torah channel that the rabbi said to his audience that at the end of days the Noahides that eat pork will not be part of the Messianic age. Because Messiah will allow them to become Jewish at later time. Is there any source for this? You have to ask the rabbi that said it. I never heard of such a thing. A Noahide is allowed to eat pork because he's allowed to eat whatever he wants as long as he's not eating an animal while it's still alive. So to say that they're not allowed to eat pork it's doesn't make any sense and I never heard of such a thing. And I can't answer other people's creations. I can only answer things that are from the Torah that I know.
