Description
Upgrade your Mercedes-AMG M156 engine with PTG CNC Ported Heads, engineered for maximum airflow, efficiency, and durability. Designed for extreme performance applications, these fully blueprinted cylinder heads are precision-machined using 5-axis CNC technology to optimize intake and exhaust flow. Whether you're running a naturally aspirated setup or forced induction, these heads are designed to deliver significant power gains while maintaining reliability.
Each set of CNC-ported heads undergoes an extensive overhaul to ensure flawless performance. The process includes full disassembly, CNC porting, a five-angle valve job, high-pressure cleaning, deck resurfacing for perfect straightness, installation of new OEM valve seals, a complete inspection of springs and valves, precise valve height measurement, and chamber CC verification. The result is a set of high-flow, high-performance cylinder heads capable of exceeding 400 CFM at .550" lift with a 2.0" exhaust pipe.
