I am looking for a good set up for the stock cams, good torque but I don't want to loose any up top. This is a street bike but ride hard now and then stock #s are 104/100 and I have seen alot of different settings 107/103, 108/102.5 Dale walker says to use 105/105. could someone explain what numbers make torque and what makes HP up Top.

For the street 105/105 is pretty good, the 108/102.5 will be up top power with a pretty wide torque curve but not make a high torque number. The higher the number on the intake the more up top and vise versa. The higher the exhaust number the broader the torque curve, but not as much torque as at 100.
