Frank Racing Inc Cylinder Head Photos

Frank Racing Inc has raised the bar when it comes to cylinder heads. FRI offers 3 different type of port jobs for the 3rd Generation Hemi Engines. Each cylinder head is hand ported in house by Steve Frank. Once the porting is completed, the head is then assembled to the specs needed to support the customers build taking into account the camshaft the customer is running, the cubic inch of the motor as well as the weight of the vehicle. No cylinder heads are CNC'd by FRI.

In this thread, I will be able to show all the forum members the differences of the ENTIRE cylinder head with photos!

FRI offers the following port designs:

• Econo
• Street
• Extreme

Here is all the images in the order of the different levels of porting. All the images below of our Show Cylinder Head that we have on display here in Houston TX for all our customers to see the differences side by side. The show head is a 6.1L Cylinder Head.

Lets start with the Intake Runner

Left to Right--> Stock - Econo - Street - Extreme

Next up... Exhaust Runner

Left to Right --> Extreme - Street - Econo - Stock

Finally... Chamber Work...

Left to Right --> Extreme - Street - Econo - Stock

Now lets narrow it down to the runners, the bowls and the chamber individually so members can see the amount of work down to each head.

I hope this helps all those interested in Cylinder heads for their vehicle. FRI takes great pride in our cylinder heads. Each cylinder head is hand ported inhouse by Steve Frank. None of our cylinder heads are CNC'd and all of are heads are made to order.
