Description
6.7 CR Stage 1 Cummins Performance Head Our 6.7 CR Stage 1 Cummins Performance Head is a step up in performance without the extra expense and work involved with an aftermarket intake. This head includes everything in our HP Reman Head along with 105-pound valve springs and a 5-axis port job while retaining the factory intake plenum. This increases the flow on the intake from around 155 CFM stock to 220 CFM, enhancing low-end performance, decreasing boost pressure, and lowering EGTs.
Features
- Enhanced Performance: Upgraded to 105-pound valve springs, a 5-axis CNC port job, and thread in soft plugs.
- Comprehensive Upgrades: Includes all features of our HP Reman Head.
