<VV> Overheating - was Deflashing Heads

[Bill H.]

           B"H

Thanks JR.  I did get to see some pics on the Net of a head before it was 
deflashed.  Pretty awful that Chevy didn't bother to clean them up before they 
left Tonawanda.  Yes, I intend to take the top shrouds off (next to the fan) as 
well as the bottoms, and see what's (literally) "cooking" under there (besides 
my oil!).

Bill

Most likely a rodent or some other creature was living on top of the right 
(probably both) heads.  You need to remove the top shroud (around the fan) and 
clean everything out with a vacuum cleaner - pressure washer - whatever you've 
got available.  Do NOT drive this car until you've completed this task - about a 
day's work for a novice.  Overheating leads to dropped valve seats and that is 
even more work (and some - not insignificant) expense.

Later, JR
