exhaust manifold removal

[Mark McDonald <tomswift@xxxxxxxxxxxxx>]

I'm sure someone else has already touched on this, but in my opinion 
the key to changing this gasket is getting the exhaust manifold planed 
before you put it back on.  Usually they warp a bit from constant 
heating and cooling, and if you want a tight seal you need to get it 
planed.  Or you could take a straight edge, like a good steel ruler, 
and check to see how straight it is, but generally I think they require 
planing, which is something I don't think you can do yourself.  (Well, 
I can't)
