Women come and go, build your car the way you want it.
Really, you have to decide what you are going to spin the motor to. The F-cam is rated from 2800 - 6000rpm and X-cam is rated to 3500 - 6500. The lift is a little nicer, but are you really going to spin the motor that high to take advantage of the X? What do you want?
