VAC Tech Tip:
Simply improving airflow is not enough, our heads are designed around improving velocity as well! Stage 2 is a great match for performance cams and/or internals. Our VAC multi-angle & Radius valve job is superior in every facet of performance to all other multi-angle valve jobs we have studied & tested.
