<VV> Valve covers

[Stephen Upham]

I'm thinking about putting on the valve covers offered by Clarks which 
are finned in order to increase the oil cooling capacity of the covers. 
  Any experience with these covers and insights gained would be 
appreciated.  ie. Do they significantly reduce oil operating 
temperature, function well, ect.  Is this something that can be done 
relatively easily with the engine in the car, or should I do it now 
that I'm in the middle of an overhaul?  I would also like to install 
the finned oil pan, but I understand that it will hang down another 1 
1/2 inch below the car.  Is this a concern or not?
