In this, episode 32 of PowerTec 10, DV explains how to get a much more 'power friendly' intake port by filling the 'lazy' parts of the intake port and cutting the 'exessivly busy' areas. Follow DV's guide lines shown here and the results will be more flow, port velocity, port energy, and port energy density. Just so you know, this all adds up to more power and torque - as well as a wider rpm range!
