Mike: I haven't read the responses, so I'm probably repeating suggestions that have all ready been made. First off, you're using moly rings, so the rings will seat quickly. Next, what you said about idling the engine at 2,000 rpm is correct. Do it for at least 20 minutes. By the way, this is to break in the cam (flat tappet) and not seat the rings. After this, check for leaks, snug the hose clamps, then go out for a ride, but avoid wide-open throttle. Instead, use moderate throttle at moderate speeds, accelerate moderately and decelerate frequently, but don't go too far from home. Once you've operated the engine for about 200 miles using this procedure, get on it!
Have fun.
