6.0 Power Stroke Warpath™ Stage 2 Cylinder Heads

The DDPM Warpath™ Stage 2 Cylinder Heads were developed for street and performance 6.0 Power Stroke applications where increased airflow is needed without moving to a full race-port cylinder head.

Warpath uses CNC-developed intake bowls, short-side transitions, and exhaust ports to improve airflow throughout the usable valve-lift range while leaving the intake runner largely OEM in size and character.

Every Warpath port design is developed and validated in-house on our SuperFlow SF-750 flow bench before being converted into a repeatable CNC program.

CNC Port Development

Warpath Stage 2 uses repeatable CNC machining rather than hand-porting production heads.

CNC development concentrates material removal in the areas identified during flow-bench testing, including the intake bowl, short-side transition, and exhaust port.

This allows us to reproduce the developed port geometry consistently from one cylinder head to the next while retaining the intake-runner characteristics we want in a street-oriented Stage 2 cylinder head.

SuperFlow SF-750 Flow Data — 28” H₂O

All airflow testing performed in-house on our SuperFlow SF-750 and corrected to 28” H₂O.

Real Flow-Tested Performance

At DDPM, airflow claims are backed by real testing.

Warpath™ Stage 2 was developed and validated using measured airflow data and SuperFlow 750 testing corrected to 28″ H₂O.

Intake Flow @ 28″ H₂O

Exhaust Flow @ 28″ H₂O

Peak airflow is important.

But what makes Warpath™ impressive is the shape of the curve.

• Strong low-lift performance
• Excellent mid-lift gains
• Smooth airflow progression
• Strong exhaust support

This creates a cylinder head designed for real-world performance rather than airflow marketing alone.

Warpath was developed around the complete airflow curve rather than a single peak-CFM number. The port shows progressive airflow gains throughout the usable lift range while retaining the OEM-style intake-runner dimensions appropriate for a street-oriented Stage 2 cylinder head.

Engineered With Casting Integrity in Mind

Port development isn’t only about airflow. Material removal is controlled to maintain critical casting integrity around the port, valve-seat, and surrounding areas while producing repeatable airflow improvements.

Recommended Applications

Warpath Stage 2 is designed for street and performance 6.0 Power Stroke builds, including daily-driven trucks, towing applications, compound-turbo combinations, performance rebuilds, and higher-horsepower street applications.

For combinations requiring substantially more airflow and more extensive intake-runner development, see our Black Label™ Stage 3 Cylinder Heads.

Frequently Asked Questions

Are Warpath heads fully CNC ported?
Warpath uses CNC development in the areas where our testing showed meaningful airflow improvements, including the intake bowl, short-side transition, and exhaust port. The intake runner remains largely OEM in size and character.

Are these hand ported?
No. The developed port geometry is reproduced through CNC machining for consistency from one cylinder head to the next.

Are the published flow numbers actually tested by DDPM?
Yes. Warpath was developed and tested in-house on our SuperFlow SF-750 flow bench. Published airflow data is corrected to 28” H₂O.

What’s the difference between Warpath and Black Label?
Warpath is our street-oriented Stage 2 cylinder head and retains a largely OEM-style intake runner. Black Label Stage 3 receives substantially more extensive port development and is intended for combinations requiring greater airflow.
