Also, does anyone know if pre-made Headers are available for the 75
Imperial as I'm planning to go dual with FlowMasters, so maybe that would be a
better solution?

Subject: Re: IML:440 exhaust manifold
question...
Another problem my 75 Imperial has is that there is a severe exhaust leak
from the drivers side. I thought it was the "doughnut" gasket but feeling
around the joint with my hand while the engine is running from underneath I
feel no air escaping so I don't think it's that...someone told me that these
manifolds have a tendency to crack and that almost certainly that will be my
problem once I take it off and see.......Is this true, that these manifolds
like to crack on the inside?...If so I would like to get one ahead of time so
as not to be waiting for it in the spring when I redo the exhaust to dual and
deal with this leak....I tried to spot a part number on it but I don't really
see any exept a very blury unreadable one towards the front of the manifold
which looks more like some kind of casting code rather than a part
number....Does anyone know what the part number would be for this drivers side
manifold and where to get one other than ebay..also from what years and
models of cars did they use this same manifold?..thanks for any help in
advance!
