DDPM - Dynamic Diesel Performance & Machine

Quality is in the details. 🔧
Precision machining. Tight tolerances. No shortcuts.
Just another day at DDPM.

PROVEN AT 1,326 HP ON FUEL. 🔥

With 430/150 7mm injectors!

The DDPM 6.0L/6.4L Stage 2 Full Valvetrain Kit was just put to the test in Gavin Ferguson’s 6.0 Power Stroke — laying down an incredible 1,326 HP / 1,844 TQ on fuel and 1,820 HP / 2,427 TQ on spray.

The same Stage 2 valvetrain package we offer every day:

🔧 DDPM Stage 2 Billet Camshaft
🔧 100 lb Pacalloy Valve Springs
🔧 Billet Chromoly Pushrods
🔧 Heavy-Duty Roller Lifters

Street. Tow. Race. Proven at four-digit horsepower.

DDPM — Engineered to Endure. Built to Perform.

OBSESSED WITH AIRFLOW. 🔧

We’re not interested in chasing one impressive peak CFM number.

Our ports are developed by hand and proven through constant flow-bench testing, with a focus on usable airflow through the actual valve events and what a high-boost, direct-injected diesel really needs.

Airflow, velocity, swirl, cylinder filling and pumping losses all have to work together — but not every variable carries the same importance in every application, despite what’s often preached.

We’ll never stop testing, learning and developing to bring you the best cylinder head products we can build.

THE WAIT IS ALMOST OVER.

Meet the DDPM 6.0 Power Stroke Stage 4 Race Head.

For years, we’ve heard the claims that this level of airflow simply couldn’t be achieved with a stock cast-iron 6.0 Power Stroke cylinder head.

Well… here it is.

🔥 240 CFM Intake
🔥 195 CFM Exhaust
🔥 2mm Oversized Valves
🔥 All-New Port Design
🔥 Stock Cast-Iron Foundation

Arguably the baddest iron cylinder head ever developed for the 6.0 Power Stroke platform.

This program was developed for one purpose: maximum airflow and maximum horsepower.

This isn’t a head for the average street truck.

It’s built for big compounds, large single turbos, nitrous, and serious competition.

And here’s the scary part…

We’re still not done.

The Stage 4 program continues to evolve, and we’re already working on the next level.

Expected Release: November 2026

They said it couldn’t be done with a stock cast-iron head.

We decided to find out for ourselves.

No pressed-in valve seats. No worries about dropping a seat like some aluminum performance heads.
