I was wondering about the amount of improvement in HP and Torque if I get a 3-angle valve grind as well as an Extrude Hone the heads. I currently (since 10/8 own a 6000 STE which I love to drive in the windy twisty sections of roads I find near my home. Any answers would be much appreciated.
Most Sincerely,
