Well, this is a 6cyl BMW.  If it were a 2002 or a 320i I would have 
no trouble getting an affordable header.  However the headers that 
are available for the sixes generally specialized and very pricey.  
Try $500+.

This, of course, was my first thought as well.  The parts for this 
car are so extremely expensive, however, that I must determine a way 
to make it work with the parts I have.

BTW, I tightened the AFM spring two notches (this one is so much 
easier to work with than the Nissan units :), and I set the jumper 
for high-altitude which should lean it a bit.  After checking the 
plugs to see the conditions of the car's mixture from before these 
changes, it appeared that the mix was pretty close.  The deposits, 
although extremely heavy, were tan.

Thanks for the advice.
