392 Early Hemi CNC Program Coming Soon

The 392 head has a need to be filled based on all of the phone calls and emails received. I’m in the process of developing a CNC Programs for this head. The Street Port is based around a 2.125 intake valve size and flows 320 cfm @ .650 lift (300 cfm @ .500 lift). For reference this head peak flows around 225cfm in as cast form. This would be a good all around option for Street Rodders looking for a nice power gain while retaining the factory castings or for Blown 392’s built for the street.
