<VV> Exhaust Log change

Sometimes the exhaust stacks (between the head and the manifold) are rusted 
to the point of uselessness.  The collar for retaining the donut 
(seal-gasket) is what usually goes away.  If any of those need to be changed 
out, you will have to at least partially pull the pushrod tube.  Note that 
the stacks have a flat side for the tube to clear the stacks  - so they must 
be properly oriented upon install.  When you pull the manifolds you will be 
able to see the condition of the stacks.  If the stacks are all fine, there 
is not much to the job of swapping out the manifolds.  Three clamps hold 
each in place - but be sure the manifolds are snug against those donuts (use 
new ones) before you tighten the clamps.  A hammer helps to seat them, but 
don't get overly aggressive with the hammer blows.

Later, JR
