Cfm head porting

Out of the box, these heads flowed a little less than I expected. However, applying the basic porting techniques, I produced a bigger gain than with many of the other heads in this chapter. With a 2.19/1.88-inch valve combo, the ported Liberty heads delivered 340 cfm at 0.700 lift, and with my seat job, 157 cfm at 0.200 lift.
