If you are rebuilding a 6.7L Cummins and plan on using some aftermarket upgrades, you need an engine that can handle the extra power you have planned. Get cylinder heads that are built for performance with Industrial Injection's Stage 1 Ported and Polished Cylinder Head With Fire Rings. These cylinder heads are what you need to make sure your engine is ready to push it's limits.

NOTE: Installation of a fire ring gasket requires high yield head studs to ensure proper seat of the head to the cylinder block.

Unlock the full performance potential of your diesel engine with the Industrial Injection 6.7L Cummins Performance Cylinder Head. Designed for Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins engine, this upgraded cylinder head features precision CNC porting, high-performance valvetrain components, and fire ring groove machining to handle higher boost levels and increased combustion pressure.

Each cylinder head is thoroughly inspected, cleaned, and precision-machined before assembly. The ports are developed using a SuperFlow flow bench and then machined with a 5-axis CNC cylinder head porting machine to ensure consistent airflow across all cylinders. This process helps balance cylinder power, improve airflow efficiency, and support higher horsepower applications.

Precision CNC Porting for Maximum Airflow

The performance gains of this Cummins cylinder head come from its CNC ported intake and exhaust runners. Using advanced CAD/CAM software and a 5-axis machining process ensures that every port flows evenly, which improves engine balance and overall efficiency. After the CNC process is complete, each port is hand blended to optimize airflow and maintain proper casting thickness for long-term durability.

Unlike aggressive porting methods that sacrifice casting strength, Industrial Injection engineers carefully balance airflow gains with structural integrity. This helps prevent cracking caused by the extreme thermal stress often found in high-performance diesel engines.

Built for High Boost Cummins Builds

This ported 6.7 Cummins cylinder head is ideal for trucks running upgraded turbos, injectors, and fueling systems. The improved airflow supports higher horsepower levels while the upgraded valves, guides, and valve seats help ensure long-term durability in demanding diesel performance applications.

Color is not accurate
Size: Medium, Color: Grey
Suit quality is good. This is NOT dark grey. Its a very standard grey when you have it in person. I might return just for this reason as we were really looking for a dark grey suit.

Stylish, Well-Made, and Comfortable!
Size: XX-Large, Color: Black
I recently purchased this 3-piece suit for my grandson, and I’m very impressed with the quality and fit. The fabric feels durable yet soft, and the tailoring gives it a sharp, modern look without feeling too stiff. The vest adds a classic touch and elevates the overall style. The sizing was accurate, and the suit was comfortable to wear for long hours at work and events. The jacket, pants, and vest all coordinate perfectly, and I appreciate the attention to detail, like the lining and buttons. Whether you’re attending a wedding, business meeting, or formal event, this suit looks expensive without breaking the bank. Highly recommend for anyone looking for a versatile, stylish 3-piece suit!

The colour was perfect for my husband on our wedding day. The material was very soft and nice. Easy to press. Was not too thick. We love it. Perfect stretch quality. It was worth the money. Didn't wrinkle easily. It was the perfect fit.

Pretty good suit
Size: X-Small, Color: Beige
These suits are great. My groomsmen wore them and everyone looked so sharp. They may need to be tailored to get a good fit for some persons though

Gets the job done.
Size: Large, Color: Deep Blue, Size: Large, Color: Deep Blue
Better than I expected (for a last minute buy). Looks great after I steamed it. Not the most durable, but a solid piece for the price. Thick and breathable material. I’m a 42R and the fit was perfect with no alterations needed.
