The answer, my friend, is to raise the rev-limiter 300rpm. You enjoy the torque multiplication in-gear, and you shift around the same time as the stocker. So every gear you put distance on him. Have been doing this since 2005 with my E46 M3, and have all the data to prove it. And no, there is no issue with the valvetrain when revving higher. Over a sample of 3 cars we have tested over 130 000km of revving 8500-8600 every day for 3 years with no ill-effects. Schrick state the stock valve springs are good for 8800rpm on the S54.
