07.5-18 Dodge 6.7L Cummins D&J Stage 1 Performance Cylinder Head

6.7 CR Stage 1 Cummins Performance Head: Upgrade your truck's performance and reliability with our 6.7 CR Stage 1 Cummins Performance Head. D&J Precision Machine is the gold standard in the Cummins performance industry.

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. This, in turn, increases the amount of fuel you can burn, allowing you to make more power.
