<VV> Overheating - was Deflashing Heads

[J R Read_HML]

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
