Finding the most available air flow is our main goal with each Cylinder head ported at Dr. J’s performance. We take the time to develop and test the ports on each individual head using all the tools available today. Every head is flow tested on our Superflow 600. And we provide you with before and after flow numbers. We also have  the ability to select camshaft and create performance estimates based  on your engine combination. Weather your heads are aluminum or cast  iron Dr. J’s can get you churpin those gears and pullin brodies. If  you would like to have your heads ported please feel free to contact  us at This e-mail address is being protected from spam bots, you need JavaScript enabled to view it

 

The Dr. Air Velocity Probe is used on all of the heads we port.  The advantage in using the Velocity probe is that is give us the ability to see where the air is moving fast or slow in the port.

At Dr. J’s we look at cylinder head porting from a different perspective. We do not use “The Force” or “Black Magic” to port your cylinder heads, we use science. Air flow is a science not a black art.
