By the way regarding the possible loss of revs at top end useing 180 degree system: I did not notice a drop changing over to the exhaust and Webbers on my old motor.But then it was pretty std. and also my 180 degree as u can see,is the old design of Hall's,( Not yet ceramic coated...) not the newer system available these days, which is different,- with what appears to be shorter header pipes ending much closer to the back of the motor itself. What system are u using and how far are u at present? Please post pics if poss.
