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:
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.
Machine for Threaded Freeze Plugs:
The freeze plug locations will be CNC machined to accept our Threaded and Oringed Mazworx Freeze Plugs
Port and Polish:
Stage 1 port is just the cleaning of the casting marks in the port. We open the seat to match the valves. This increase air flow across the seat and this port is done by hand.
CNC Combustion Chamber:
This process opens up your combustion chamber and removes the squish areas. The squish areas are there for low rpm tumbling of the air fuel mixture, but at high boost, they become a hot spot. This leads to detonation. Plus opening up the chamber deshrouds the valves and allows them to breath better.
The process can be viewed here: Mazworx CNC Combustion Chamber
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.
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.
