The only drawbacks are the possible need for premium fuel if you want to advance it farther than regular fuel can stand.
You will gain some performance and response increase when advancing the timing.
If your timing mark seems to flutter wildly when you are checking the timing with a timing light, this could be an indication of a loose/sloppy timing chain which should be replaced.
The range I have seen stated most often is 12-16 degrees which is 2-6 degrees over the stock setting of 10 degrees BTDC.
Listen carefully for the engine to "spark knock" or "ping".
If it does then you will need to either ****** the timing a degree or two, or run a higher octane fuel.
