<VV> Engine issue / Head Flash!

[Matt Nall]

Have you checked for casting flash in the head of the left bank?  You 
mentioned "cleaned the fins", but I'm not sure exactly what you meant by 
that.  You blew out debris with compressed air?  You did something more than 
that?

It is common for "flash" to remain in the heads which blocks the NEEDED 
cooling air flow.  You should be able to clearly see through the passages 
(all of them) in the head by putting a light below and looking down from the 
top (left side carb and shroud removed).  So, if the head has not been 
"de-flashed" that could be a big part of your overheat problem.
