The tri-ys are perfect for the application you are running. Even with a stock to decent cam, you will have good bottom end torque. Why do you want midrange to hi-rpm power band? Unless you are going to be racing in that upper RPM band. The full-length headers do offer better upper RPM torque, but at a loss of torque from 1200-4500 rpms.
