74 360 Engine Vacuum Hoses Missing

["Greg Schroeder" <gschroeder@comcast.net>]

While replacing the thermostat and installing an electronic ignition I noticed
some of the vacuum hoses were cut and a screw was inserted. When I go through
the manual and check for the hoses I see several rerouted and others that are
missing.  The engine appears to be running fine.  How important are the hoses
to be correct in the correct places?  What would I notice as something that is
not working correctly?
