[alfa] exhaust manifold-to-head sealing, GTV-6

[Joe Elliott <jee@xxxxxxxxxxxxxx>]

In my previous experience, the copper gaskets between the exhaust 
manifolds and the cylinder heads on my GTV-6 always crush down to the 
thickness of the copper they're stamped from.  On the spare engine 
that I'm (still!) swapping into the car, several of them didn't seem 
to crush down all the way.  This wouldn't bother me, except that it 
only happens on the bolted side of any given flange, which led me to 
believe that it was a problem with a the threads in the head that 
those bolts go into.  But now I've pretty much ruled that out.  I 
made a point to ensure that the flanges were good and clean, so I'm 
not sure what's going on here besides me being anal and noticing 
something that I just never noticed before.  I'd like to be certain 
that it's not going to leak exhaust when I finally get it installed.

Any thoughts?
