Our ported cylinder head program is nearing completion. We have flow numbers for the stock Zetec head, stock Zetec SVT head and will be flowing a Ford Racing CNC head this coming week. Our goal is to provide a cylinder head that has equivalent or better numbers than the Ford Racing head for the same price or less. We are planning on offering different stages to meet different needs.
