To the point that I have head lights (standard sealed beam) flickering like improperly wired LEDs. Probably just gonna get a new 80-100 amp alt... Idk

Yeah, a larger alternator won't fix your problem. As already suggested, the easiest and least expensive fix is to first look at the quality of the connections, especially grounds. It is not uncommon for the plugs on the headlights themselves to get corroded and cause a lot of resistance and thus causing issues like yours.
