That's fairly normal before the valves and rings seat, i would run the car for a bit and give it a chance to seal up. Let the motor cool and get the number. if those are your numbers after already doing that then its a different story. generally motors we build are 1-2% leak-down while on the engine stand and that drops to 1 or less once the motor is ran.
