The late '63 or 64 and newer heads have six attachment points for the leaking 
valve covers that will still leak or seep any ole way ( but not as much or 
often ).  The valve covers used through the 66 model year Imperial will hold the 
spark plug wires out as your present assembly.  Starting in 1967 the Imperial 
wires were routed different.

You did not mention anything about the cam.  If you change the cam bearings, 
then you are going to change the cam.  The best cam for your heavy car is the 
RV/ torque cam offered by MoPar Performance ( #  P4286675  260/260 @ .430 lift 
).  Other cams may seem tempting but the best bang for the buck is above due 
to your weight.

The intake manifold was designed for torque also.  Don't make the mistake of  
paying for a newer intake manifold for the carb has a differant bolt pattern 
and neck size.  You will be trying to re-do the linkage and looking for a air 
cleaner housing that is large enough for the carb neck.

The one thing that you can do is to switch the exh manifolds for the late 
model big block trucks on the drivers side ( they are center dump as your car is 
now ) and the   matching in design that came on the last years of any MoPar 
big block regular 400 or 440.  If you do this you will not be able to use the 
gen and then you must go to the alt if yours is a real early issue.
