Maybe someone just bolted alot of parts together for a conversation piece? Inquiring minds want to know...

They had siamesed exhaust ports and, in some cases, intake ports. Pretty common at one time. VW guys extol the virture of "single port" and "dual port" heads for different applications. The single ports shared a common intake port that branched inside the head. I've seen this on an old Landcruiser straight six as well, with shared intake ports between the 2/3 and 4/5 cylinders.
