The AMG GT platform demands heads that can flow under sustained high-RPM, high-boost, high-heat conditions — lap after lap. Our M178 CNC-ported heads are flow-bench developed for the dry-sump 4.0L V8, assembled with upgraded valvetrain, and sold as a matched pair. Built at YPG Motorsport in Kuwait, shipped worldwide. What Are CNC-Ported Heads? CNC porting reshapes the intake and exhaust ports using computer-controlled machining to our flow-bench program. Every port is cut to identical runner volumes and matched flow rates across all eight cylinders. On a twin-turbo engine like the M178, ported heads reduce pumping losses, improve turbo spool, and...

On a turbocharged engine, the heads are not just an airflow component — they are a thermal management system. Our M177 CNC-ported heads are flow-bench developed and assembled with upgraded valvetrain to reduce pumping losses, improve spool, and let your turbos push more air through the combustion chambers efficiently. Built at YPG Motorsport in Kuwait, sold as a pair. What Are CNC-Ported Heads? CNC porting reshapes the intake and exhaust ports using computer-controlled machining.

The factory M156 cylinder heads flow well from the factory — but "well" is not "race-ready." Our M156 CNC-ported heads are flow-bench developed, precision-machined, and assembled with upgraded valvetrain to unlock the airflow your forged bottom end needs. Built in-house at YPG Motorsport in Kuwait, sold as a pair, and shipped worldwide. What Are CNC-Ported Heads? CNC porting uses computer-controlled machining to reshape the intake and exhaust ports inside your cylinder heads. Every port is cut to our proven flow-bench program — identical runner volumes, matched flow rates across all eight cylinders. The result is more air in, more exhaust...
