This is the head we use for all of our big boost engines other than the ones with billet blocks and no water. They have great airflow (see Airflow Chart in Photo Set) and are amazingly strong. Here's why:
- 100% virgin Alcoa aluminum ingot with no remelt
- Heads have been HIP treated (hot isostatic pressing) for greater strength and dimensional stability
- Up to 1 inch deck thickness, 0.75 inch minimum
- Enhanced six-bolt design
We buy these heads as porter castings and are therfore able to impart our own designs when we machine them on our 5-axis CNC. Our Newen CNC seat & guide machine does the valve job and bowl blending in one operation. The port volumes after machining are 290cc and 108cc respectively for Intake and Exhaust.
