one step ahead of ya mate

, im planning on getting a wiend x-celerator, because i have heard(off here) that they are a good monifold for running straight gas through(which i plan to do)
i think i know the difference between 2v and 4v's ... its the valve size isnt it? (or also used to describe 4 venturi by ford in the seventies after they stop using actualy 4v heads)
correct me if im wrong.
