Used those on my bug engines.  The effect was fine with the bug and did have
a noticable performance change.  However when they were added to a bay bus
with the older 1600 engine they had no effect at all.  I would say that with
the even heavier mass of the vanagon that the effect would also be nil
except that there is a higher wear associated with their use on the valve
train.

For the vanagon you would be better off with big valve heads and a proper
cam for them.
