Laydon....... Thanks for picking up on that and for the photos. I will correct that post. I had forgotten all about this style head. I have seen this illustration before and thought that it might be strictly a racing head with no provisions for an exhaust manifold as in photo 1. Or being an artists rendering the flanges and bolt holes were omitted. I also noticed that this is dated 1918 whereas the Model B catalog is dated 1919.
The other thing to note is the Model A used the Ford intake and exhaust ports for eight intake ports which are covered by one intake manifold, photo 2.
In looking around the web I found this photo of what appears to be a Model A Roof with a proper manifold for a road car. Photo 3
Photo 4 shows the intake side of a display at Bill Smiths Museum.
