Rottler P69AHD 5 Axis CNC Cylinder Head Porting
& Multi Purpose Machining Center

We can Digitize, ie. Digitally Copy, our Hand Ported Cylinder Head Ports and Combustion Chambers right on the machine using a Reinshaw Probe. All data is then generated on screen, and edited if needed to make improvements of the port design, then toolpaths are created so you can load a head and start machining away.

This page will be constantly updated as new head and port designs are made.

Please check back often, or call the shop to suggest a new head. Thank you ! , Larry's Auto Machine

Service Includes:
Precision CNC Porting Customer Supplied Cylinder Head.

* This service does NOT include Head Casting, Disassembly or Assembly, Precision Multi-Angle Valve Job, or Resurfacing. This is for the Porting Service Only. All other machine work is extra charge.

* Please note, It's not uncommon to see certain parts of the ports that are not machined. This is because with most of our port designs we try to keep port velocity to a maximum, It's not always about how big the port is, or maximum flow numbers. This almost always helps with low to midrange HP and Torque numbers without sacrificing top end.
