Mark, Remember that discussion we had just over a year ago, in which you re-ran your desktop dyno using 140 hp valve sizes? If I remember correctly, there was a significant gain in torque and horsepower, throughout the rpm range. It also rendered a flatter peak torque curve, also right at the peak of the usable rpm range. Since any engine is basicly an air pump, it makes sense that if you increase the displacement of the pump, you should also increase the breathing capacity (valve size) accordingly, so putting 140 hp size stainless steel valves and new deep valve seats would be my first consideration.

Probably, but I wouldn't recommend it to mere mortals. A few weeks ago I had dragged out my spare 95 hp engine and was very close to rebuilding it as a 2700cc engine, if that gives you a clue.
