In the  process of replacing exhaust system. Kind of
tough… original exhaust pipes,  nuts and bolts rusted
pretty well, etc.

Here is my question: is  there a certain configuration
of the studs/nuts and bolts that hold the  crossover
pipes on the cylinders? Right now,
Cylinder #1 has    1 stud (upper) & 1 bolt (lower)
Cylinder #2 has   2 studs  (both upper & lower)
Cylinder #3 has   1 bolt (upper) & 1  stud (lower)
Cylinder #4 has   2 bolts (both upper &  lower)

I am asking because I am replacing all studs/nuts and
bolts  with stainless steel, so, 21 years from now I
may not have such a hard time  taking them apart ..
haha! ETKA and Bentley are not very clear on  that.

Also, it looks like the bolts should be 30mm and the
studs  should be 40mm. True?

My  advice is to use only 30mm bolts in all locations.  This allows easy  
replacement of a flange gasket or removal of a head if need be in the  future.  I 
think the only reason VW used studs on the one head was for ease  of assembly 
on the assembly line.
