[V8] Heat Soaking V8

Has anyone had any issue with shutting off a hot engine?  Say 100 or 
slightly warmer?  I'm not sure how to cool it off before turning it off, 
idling seems to raise temp more than anything.  Right now, if I Turn it 
off at 100, it'll soak up to about 105 then cool down but it's only been 
70 out.  I'm worried about triple digits.

I know some cars have the cooling fan hooked up to kick on (at least) a 
low speed even with the ignition off to help cool off an over-hot car. 

How does the V8 deal with the expanding pressure?  There doesn't seem to 
be a "bleed line" coming from the cap.  Is it pressure rated to release 
pressure (at 16 lbs., e.g.), or if not, how does the system ease pressure?
