Really? When I look at the VW head image, I see two cylinder heads cast
together in a manner that reduces the total fin area and obstructs
cooling flow. I see a cylinder head with cylinder stud bosses that not
only reduce fin area, but are actually blocking cooling air just where
it is needed. Same with the studs themselves. I see a cylinder head
with a single pompadour cooling fin in the extremely critical area
between the valves and spark plug boss. If you could actually hold a
C-85 and VW both in your hand the differences would be even more striking.
