360, LA360, or Magnum 360?

Well one my old motor was tired lol. But this is my first roller cam. If I'm correct rollers get lower RPMs quicker but you can't take they as high safely as a solid? I use to run myother mopars up to 7000 with solid lol only broke a motor once. Threw a main bearing in my charger se 400 seeing if it would max out the 150 Speedo it passed the mark then killed over lol I'm dumb occasionally but that's how we learn.
