Will I benefit from adding more of my Main Vent?

My main vent is 2 x Gorton #2. The main pipe is about 25 feet. Boiler is over sized and the radiator vents are noisy.

    Pitch on the header may look weird and I hate weird angles and crooked stuff.

    But that being said the equalizer end of the header must be the low end

    pictures will help
