Old legend

After taking one of the heads off to get to the valve tappets. I took it for a short ride (5 miles), checked for leaks, took it for another short ride (10 miles), checked for leaks again and all seems ok. I had changed from Harley 360 oil to Screaming Eagle Synthetic and the engine actually seems quieter than it was (Although the pipes still sound strong ). My question is do I have to go through a break in period before I start riding a lot or running it on the freeway?
