PIE SuperTune MAXPORT SERIES Cylinder Heads

Our MAXPORT SERIES cylinder heads are the ultimate, highest-flowing versions of our SuperTune research, design and development program. Each of these cylinder head families represent the best flow possible that we've found from their respective designs. And each one is the result of time, painstakingly dedicated to airflow testing, port modification and, in some cases, extensively reworked or completely new, proprietary castings. We welcome you to learn more about the heads that best suit your application and are always happy to answer any questions you have.

NOTE: Our MAXPORT TNT Big Block heads are exclusive to PIE and cast only for us. We have installed them on a few customer engines and will be releasing them soon for sale to anyone looking to bolt explosive power onto their Big Block MOPAR.
