Before you do anything as drastic as rebuild the engine, let's first define how it is running right now. What kind of mileage are you experiencing right now?

Are you burning any oil? How much. If you aren't burning significant oil you probably aren't going to gain anything in terms of mileage by rebuilding the engine.

Edit

Michael and I were evidently typing at the same moment, he just got done quicker.

Mileage-related problems are most often fuel and/or ignition system problems.
