[V8Vairs] Long term engine storage - to rotate or not

[PaulSiano at aol.com]

I have received differing opinions about periodically rotating a freshly  
built engine.  One school of thought is to do it so that some valve  springs will 
not be compressed for long periods of time.  Another  suggestion is to not do 
it to avoid scraping oil off of the cylinder  walls.  Is the best answer to 
squirt oil in the spark plug holes and rotate  it every couple of weeks or so?
 
Any thoughts?
