Offered as a 215cc PRECISION as cast intake port, our port design provides positive airflow at .900 lift!

Pro-Filer has significantly improved the rocker stand area to provide more reliability for your valve train. This upgrade allows you to increase your rpm and power while still using stock components. It also features a 1/2" raised valve cover rail.
