24V Cylinder Head - Chop and Port

[sbentz]

As many of you are aware, we run a 24V head that we chopped the intake manifold off of years ago, and build a bolt on intake manifold. Many others have done the same since then. I won't say that they copied us, as it is such a common sense deal, that everyone should do the same in order to really get into the intake ports to work them over and open up #5 and #6 fully.

The real story is that I had a spare head that was cracked in the intake manifold area, and I started whacking at it with a mill to see how i could improve the airflow. Once I had the entire thing cut off, I figured I might as well use it for the race car.

We are doing another head for our new motor, and thought I would put up some photos as it comes together to show how the ports look inside.

I would never do this for a street truck, or anything less that a full out deal. At 80 PSI with a set of twins, porting makes a small amount of difference compared to the cost and time to do it.
