When we removed the factory two barrel on my son's 78 Matador, there was a 1/4" spacer under the carb. My thinking is that the engineer would not have spent the money for the part unless there was a good reason for it. I generally use a 1/2" wood spacer on a four barrel. It definitely helped with hot starting on my son's 360.
