Our new CVN style cylinder head intake port flows even more air then our J.E.T. high velocity intake port modifications. 

Q. Why is the new design named CVN?
A. When all was designed and flowed, Bob looked at the port and decided it looked like the front of an American Aircraft Carrier. The letters CVN are simply the alpha designation the US NAVY gave these carriers.

The new J.E.T. CNC ported and hand blended CVN intake port gives the intake charge a more direct path into the cylinder. Large port cylinder heads cause the air to flow across the intake valve. J.E.T. has designed more aerodynamic ports that get air into the cylinder at higher velocities resulting in more torque and more horsepower everywhere. This modification flows air past +.600 valve lift.  Take a look at our rough illustrations of what we mean, hopefully the drawings are helpful.  You can click on the images for a larger view.
