more important than head porting is a top-notch valve job. Radiused are the highest performing valve seats, and of course the blending of this into the cyl/mild portwork is a great idea for these engines. Typical results from what ive seen are in power, torque and spoolup - provided the port was not ported too heavily of course. sorry to threadjack
