There is nothing wrong with the head as long as people don't mess them up. They are big and need cautious grinding and valve choices.
The pipe is critical too. There are several that actually scavenge (some better than others) and when a cam that is used with over 30° overlap they can get soggy fast without one of these better pipes. Going to the trouble of using a good pipe (in the case of a Supertrap actually tuning the number of discs), a larger TB and equally high quality tune will net a large difference. One customer of mine did go both ways. All the right parts in the motor good tune 110hp 106TQ and a relatively flat torque curve. Changed to the factory 58mm TB, Boarzilla, larger injectors and had it retuned, 122/122. Same tuner, one of the best. You decide?
The 110 will move right up the ladder with the rest of them with careful planning and spending money on the pieces that add value.
