Hangar Flying

I have just completed a long-ez with an IO-360. I did a first flight yesterday and what happed is that over 180 mph the pilot (weight 140lbs) had to use so much forward stick to keep it from climbing even with full forward trim it was difficult to hold down and maintain level flight. 30 lbs already was added to the nose and the W&B were such that the pilot could be as light as 130 lbs. My concern is that the elevator is so far deflected up to maintain level flight at that speed that you have a lot of induced drag from the elevator. The plane was never designed to fly at those speeds so I’m thinking to adjust the ailerons slightly up to reduce lift on the main wing. Or could it be resolve by weighting the nose even more to move the CG farther forward?
