The heads are amazingly strong and 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
These All Pro LS7 cylinder heads come with shaft mount rocker provisions. Our custom CNC work brings them to their maximum performance. Being cast heads, these qualify for a 50 lb weight reduction in several race classes.
