That is part of the problem, with the VW design.

The fact that the two cylinders are combined into one unit, means that the
opportunity to get some distance between the cylinders, and thus some more
room to add more cooling fins and area to the heads. You just can not
separate them enough.

have you ever had a close look on a VW head? At least my MOFOCO head got a
gap between the front and rear cylinder. The fins actually ARE separated! I
see more an advantage than an disadvantage with the VW head. Makes the top
end much stiffer.
