Since you did not get much in the way of a response on this question,
here's my 2 cents. Yes, you can do a head gasket replacement with the
engine in the van. Assuming you enjoy working on your back with the
occasional coolant drip/stray piece of crud in your face, and the cylinders
don't stick to the heads so bad that you pull them off with the head.

As for special tools, only a torque wrench if you are only doing the head
gaskets and don't have to mess with cylinders. In my case, the
wasserleaker's heads were OK, a bad coolant pipe had been the culprit for
the coolant leak. But while I was in there, I found that one of the pistons
was about to self-destruct, necessitating the more indepth teardown. If you
are removing cylinders, especially replacing pistons, now you got a job
ahead of you. I found it much easier to just bite the bullet & pull the
whole engine. I hates standing on my head working on VW engines anymore.
After checking the price for the special Vanagon piston wristpin puller and
ring compressor, I did the job with a piece of threaded rod, some washers
and an appropriate sized socket, and a big hose clamp. The officail tools
are probably more efficient, I only expected to do this job once or twice
in my life.
