Gen 1 Mitsubishi 4G63 CNC-Ported Cylinder Head

Gen 1 Mitsubishi 4G63 CNC-Ported Cylinder Head – Fast-Track Build

This Gen 1 Mitsubishi 4G63 cylinder head has already cleared the longest part of the process and is primed for a high-level build. The head has been professionally cleaned, stripped, guides removed, and CNC ported using the same proven port design that has powered some of the world’s fastest 4G63-powered cars.

This isn’t just a “good core”—it’s a time saver. By starting with a head that’s already CNC ported, you’re skipping weeks of downtime and getting straight to the good stuff. From the time of purchase, this head can be fully completed in as little as two weeks.

 Important: This cylinder head is only available as a completed package. It is not sold unfinished.
