My 230 was bored .020 over and the head was planed slightly to flatten out a warp. The engine was also balanced.
Does anyone have an idea approximately how much additional horsepower results from these changes? I realize it is probably only a small amount. BTW the engine runs, with the balancing, with almost no perceptable vibration.
