Start it, set the timng, set the idle when it gets warmed up, shut it off, reset the valves, start it, check for leaks, go drive it. Run it up to 2500 RPM, back off the gas and let it coast down, do that 4 or 5 times, then go to 3500, back off. Alternate between pulling (not real hard, but pulling) and coasting. After that, drive it like a rental car. If it's going to crap out, it's going to do it regardless.

The 20-minute break-in is absolutely crucial for the metal to mate and the chemical process between the oil and the metal to occur creating a surface on the cam lobe.
