Swirl in head
Robert,
We're in the process of porting the cylinder head for an International pulling tractor. The stock intake port had considerable bias to induce swirl. However, we have enlarged the port considerably and plan on installing larger intake valves which will reduce the bias quite a bit. With turbo boost of 95 psi will removing most of the swirl bias hurt performance?
What will happen by not using a pressed-in seat ring on the intake valve?
Ron
