The manufacturing process of engines has come along way over the years. They are able to nail exact tolerances for mass produced engines which basically eliminates any required break in. Basically, every part is machined to such a tight clearance the only break in required is for rings which happens in the first few minutes of starting an engine.
If it makes you feel better to change your oil early then by all means do it. In this day and age early oil changes are not required. If anything I would change the filter early, if there any is any foreign material in the oil it will be trapped in the filter. Also, you have to consider the amount of oil these engines hold, it takes along time to break down 12 quarts of oil.
