Product Description

Our CR Stage 1 Cummins Performance Head is a step up in performance without the extra expense and work involved with an aftermarket intake.  Our Stage 1 Cummins Performance Head includes everything in our Performance Cummins Reman Head along with 115 pound valve springs, 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.  This increases low end performance, decreases boost pressure and lowers EGT’s, increasing the amount of fuel you can burn and make more power.
