<VV> Removal of Casting Flash

[JVHRoberts at aol.com]

Of course, anything to reduce the resistance to air flow is a good idea. 
Fortunately, and probably by design, the flash on the cylinders tends to be  
in a line, across the top and bottom of the jug, as it sits in the engine. As  
such, this doesn't block air flow, since it acts as a 'fin' parallel to the 
air  flow. 
Also, most of the heat goes out the heads anyway. 
IMHO...

Just a  thought.

There is lots of good discussion on cooling and fan options  but not one 
comment on deflashing between the cast iron cooling fins on  each cylinder to 
enhance cooling.

I seem to remember reading a  previous article in the Communiqué that stated 
flashing removal is  recommended, but do not recall if the cooling benefits 
were  quantified.

Has anyone performed a before and after casting flashing  removal comparison 
and realized any operating temperature  differences?
