HELLCAT HEADS ARE HERE!!!
Compared to the 392 Apache head, the Hellcat head looks very similar, but the Hellcat heads are cast at a specialty low volume using Hellcat specific tooling. The Apache head is a 319 alloy while the Hellcat head is a premium heat-treated 356-T6 alloy, giving it higher thermal conductivity and improved elongation (one of the measures of an alloy’s strength).
The following are some improved features of Hellcat heads over the Apache heads:
- Better material for boost
- Increased stiffness for boost
- Improved water jacket design over any previous head design for higher power levels
- Custom CNC porting by Modern Muscle Performance
- Multi angle valve job, and blended
