Jeff,
After 1,000 Km of driving a rebuilt engine, you should be able to safely switch to synthetic lubricants. You are breaknig in at a retarded timing setting to minimize load on the engine and ease the break-in process. Advancing the timing will certainly make a difference in not only power but fuel efficiency as well. If the cam is ground like many other aftermarket replacements, if has a slight valve timing advance over the stock cam unless you degreed it differently. The ignition timing can be advanced a bit more to take full advantage of that.
