<VV> Exhaust Question

[Ron]

Don't forget that there are probably no seals between the manifolds and the 
engine shrouding at the front.  High temp seals are available but few use 
them.  Without any seals, some hot engine air will be leaking out just 
behind the joints that you are having trouble with.  Take a good look at it 
as this may be IT.
