i stole that post i take no credit 
The old belief was that advancing the cam would give more low-mid power and retarding would yield a little more top end..
Based on current dyno testing, this is not the case.
Typically advancing a couple degrees will give an engine a few more hp/tq ... and retarding will yield zero to negative results.
This procedure is usually done by competition guys to squeek out each bit of power they can, and not too common with the daily driver/street crowd.
The gains aren't rewarding enough for most to do the procedure ... however if doing an engine build and swap moving it a couple degrees advanced doesn't hurt (with most grind cams) ... You should always be aware of your valve and piston clearances.
