In this article, we're taking a look at our line of Ultra Performance Cylinder Heads and what they can do for your diesel engine. 

What Are the Ultra Performance Cylinder Heads?

The Performance Line of Cylinder Heads offers some upgrades to help you get the most out of your diesel engine. 

Inconel Valves

One of the main features of this line are the inconel intake and exhaust valves. These valves are stronger and more durable than stock valves.

Inconel is considered a super alloy of blended metals. This alloy can withstand the higher temperatures and pressures produced by these turbocharged engines. 

Valves made from inconel won't bend or break like stainless steel valves can in harsh conditions. You'll often find them used in motorsports. 

Using inconel valves also reduces the risk of chordal fracture, and they're resistant to corrosion, oxidation, pitting, and cracking. 

Fire Rings

Another feature of the Performance Line of cylinder heads are Fire Rings. These stainless steel rings are machined into the deck, and they help prevent head gasket blow-out. 

Heads with these can better withstand the extreme temperatures, pressure, and stress that is generated by high-performance engines. 

What Are the Different Stages of Performance Cylinder Heads?

To begin with, all our Performance Line Cylinder Heads use the same castings to ensure proper fit and function, increased nickel content throughout the casting, and increased cooling capacity.

These heads are all brand new. That's because, over the years, we've found that welded or repaired cylinder heads are not as strong as new ones. This can result in another unwanted failure.

Standard Cylinder Head

We offer the standard cylinder head, and this head is loaded with all the new essential components you'd find in an OE quality cylinder head. 

Included with this head are:

• New intake and exhaust valves
• Valve springs
• Spring retainers
• Pre-installed cam bearings

This head is also designed with wider fluid passages and a thicker deck for enhanced coolant flow and it's crafted with a higher nickel content. This ensures increased strength and durability in the overall structure of the head.

Stage Two Cylinder Head

Next, we offer the Stage Two Cylinder Head. With this head, you'll get everything from the standard head, but you'll also be getting Inconel Exhaust valves installed.

Stage Three Cylinder Head

With the Stage Three Cylinder Head, you'll get all the standard features, as well as the Inconel Exhaust Valves, like the Stage Two Head.

On this head, though, you'll also have Inconel Intake Valves installed. Any issues the stock valves may have faced have been greatly reduced in the Stage Three Head, since all the valves have been replaced with Inconel material.

Stage Four Cylinder Head

The Stage Four, Ultra Performance Cylinder Head, is the hallmark of our Performance Line of Cylinder Heads. It comes with everything we've mentioned before: your new essential components, Inconel Intake Valves, and Inconel Exhaust Valves. 

The Stage Four Head also comes with Stainless Steel Fire Rings machined into the deck. These Fire Rings help prevent head gasket failure, a common issue caused by the extreme pressures and temperatures these cylinder heads operate in.
