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
CNC Port:
Stage 3 port is a developed level CNC port. We maximize the ports and seat to obtain the highest flow. We invest hours developing this port using our Superflow 600 flow bench.
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.
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.
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.
1/2" Head Stud Machining:
The head stud holes are drill to fit 1/2" head studs and the dowel pin locations are machined for 16mm dowels.
Surfacing:
Resurface your head using a PCD (poly-crystalline diamond) tool.
Valve Seals:
Replacing your old valve seals with new ones.
Assemble:
Installation of the valve, springs, and retainers.
Dual Guide Conversion and Set Rocker/Lash Level for Solid Pivots:
This process we will machine your rockers to accept dual guides. Then we will set the rocker level and last to the cam for the solid pivots. We will using 8 of your existing guides and provide 8 new ones to set this.
