A comparison of the stock (left) and RHS intake ports shows the difference between 205 cc and 225 cc of intake runner area in the new heads. RHS’ Kevin Feeney says, the flow numbers are conservative, as the RHS engineers focused more on the quality of the airflow, rather than just quantity. If the air speed is hindered, low-end torque suffers. Based on our numbers, we’d have to say this isn’t a problem with these heads, as our creation has plenty of low-end pull along with gobs of top end power.
