Unlock More Power: Why the 6.7 Cummins Stage 1 Performance Head is the Perfect Upgrade for Your Dodge Ram
If you're running a 2007-2018 Dodge Ram with a 6.7L Cummins and looking to boost performance without breaking the bank or tearing apart your entire engine, the Stage 1 Performance Cylinder Head might be exactly what you need. This upgrade delivers serious airflow improvements while maintaining the reliability your Cummins is known for.
What Makes the Stage 1 Head Different?
The factory 6.7 Cummins cylinder head does its job, but it leaves a lot of performance on the table. Stock heads flow approximately 155 CFM (cubic feet per minute) through the intake ports. Our Stage 1 Performance Head increases that to 220 CFM—a 42% improvement in airflow.
That's not just a number on paper. More airflow means:
- Better combustion efficiency
- Increased horsepower and torque potential
- Improved throttle response
- Better performance under load (towing, hauling)
Who Should Upgrade to a Stage 1 Head?
The Stage 1 is designed for the enthusiast who wants noticeable performance gains without going full race truck. It's ideal for:
Street and Towing Builds
If you're running moderate upgrades like a tuner, exhaust, and intake, the Stage 1 head complements those mods perfectly. It provides the airflow your engine needs to make power efficiently without requiring you to change your entire intake system.
Daily Drivers Who Want More
Unlike higher-stage heads that may require extensive supporting modifications, the Stage 1 retains compatibility with your factory intake plenum. That means you get performance gains without the headache of custom fabrication or losing streetability.
Reliability-Focused Builders
Every Stage 1 head is completely remanufactured to exacting standards. We're not just cleaning and reassembling—we're upgrading critical components to handle more power while maintaining long-term durability.
The D&J Precision Machine Difference
Not all performance heads are created equal. Here's what sets our Stage 1 apart:
Precision 5-Axis CNC Porting
We use advanced 5-axis CNC machining to reshape the intake and exhaust ports for optimal flow characteristics. This isn't hand-porting that varies from head to head—it's repeatable, precise, and engineered for maximum performance.
Upgraded 105-Pound Valve Springs
Stock valve springs can't handle increased boost and RPM. Our 105-pound springs provide the valve control you need for performance applications while preventing valve float and maintaining proper sealing.
Thread-In Soft Plugs
We replace factory freeze plugs with thread-in soft plugs for superior sealing and reliability. No more worrying about coolant leaks under pressure.
Complete Rebuild Process
Every head goes through our comprehensive remanufacturing process:
- Complete disassembly and cleaning
- Crack checking
- Installation of new bronze valve guides
- Heavy-duty extra-large valve seats
- Precision CNC valve jobs for perfect sealing
- Deck resurfacing to factory specifications
- Pressure testing to ensure zero leaks
Real-World Performance Gains
While exact horsepower gains depend on your overall setup, customers typically see:
- 20-40 HP increase when combined with supporting mods (tuner, exhaust, intake)
- Improved EGT management due to better airflow and combustion efficiency
- Better boost response from reduced intake restriction
- Smoother power delivery across the RPM range
Installation Considerations
Installing a performance cylinder head is a significant job that requires mechanical expertise. You'll need:
- Head gasket kit (we recommend our fire ring head gasket for added sealing)
- ARP head studs for proper clamping force
- Fresh coolant and oil
- Proper torque specifications and sequence
Pro Tip: Many customers opt for our "Add Fire Ring and Fire Ring Head Gasket" option when ordering, which includes everything you need for a bulletproof seal.
Stage 1 vs. Stock vs. Higher Stages: Which is Right for You?
Stock Head (155 CFM):
- Factory performance
- Good for completely stock trucks
- Limited power potential
Stage 1 Head (220 CFM):
- 42% more airflow than stock
- Perfect for 400-500 HP builds
- Retains factory intake plenum
- Best bang-for-buck upgrade
- Maintains excellent reliability
Stage 2+ Heads:
- Maximum flow for competition builds
- Requires extensive supporting mods
- May sacrifice some streetability
- Higher cost
For most enthusiasts, the Stage 1 hits the sweet spot of performance, reliability, and value.
