So did someone with a clue do a drag port on the cyls? Not knowing any specifics on the motor setup is hard to tell what you'll need. Strictly drags, you might as well run alcohol. 35-39mm alky Carbs, intakes, filters, used will run 300-600. You'll need better pipes, about 300-500 used. Post pics of bike so we can see what'll need changed chassis wise.
