Here at Mazworx, we can build your cylinder head to your specifications. Utilizing our CNC capabilities and state-of-the-art equipment, you can ensure that the machining process is done properly. If you want a cylinder head that is ready-to-bolt-on, see the specifications section for info. For more understanding of our process, see the additional information section.

Each built head will start with the following:

Hot Tank Cleaning:
Wash your head to get oil and grim off.

Sand Blast Head:
Since these heads can be over 20 years old, they may start corroding. Sand blasting the block will get the corrosion/debris off, bring a uniform satin aluminum color to the head and give it an overall better look.

R/R Oil Port Plugs/Freeze Plugs:
This process includes removing, re-tapping, and reinstall all the oil port plugs. By taking out the oil port plugs, we are better able to clean all the oil galleys. The freeze plugs are also removed and replaced.

Port and Polish:
Stage 1 port is just the blending of the seat and bowl area.  The rest of the port will stay with the OEM casting.

R/R/R Valve Guides:
This process removes, re-installs, and reams the valve guides. The guides are replaced with Supertech bronze valve guides. The DET heads typically have worn out exhaust guides after 20 years, so we change both intake and exhaust to get the head back to specification.

Upgrade to Multi Angle Valve Job:
In this process, we cut multiple angles in the valve job to help increase flow. With a 90mm chamber, we can add up to 5 angle plus a radius.

Resurface your head using a PCD (poly-crystalline diamond) tool.

Valve Seals:
Replacing your old valve seals with new ones.

Installation of the valve, springs, and retainers.

Set Rocker Level:
This process we will set the rocker level to the cam.  We will using your existing guides and shims to set this.

Parts Included:
Supertech Std Size Intake Valves
Supertech Std Size Inconel Ex Valves
Supertech Single Spring Kit and Titanium Retainers
Supertech Bronze Valve Guides
Viton Valve Seals
Oil Port Pipe Plugs
