MDS 4-cyl Duratec EVO Cylinder Head

Unique Design and Casting for
Highest Performance and Rating


Cylinder head is an all new MDS design
The head is cast in UK in high grade aluminium (AlSi7Mg0.6 material), heat treated for maximum strength.

Increased deck thickness for turbo
Up to 15 mm thick bottom deck increases the structural integrity of the casting, making the cylinder head an absolute choice for high performance and high cylinder pressure applications.

Increased casting integrity and strength
The casting strength is increased with the new design. More material around the intake and exhaust ports and cylinder head bosses. Inner bulkheads and webbing have been added as well as more material to increase wall thickness at all critically loaded areas.

Better cooling
The water jacket has an added upper gallery for good aeration. Full cross cooling (with an external feed gallery) or mixed cooling strategies are possible.

Uncompromised high flowing ports
The intake and exhaust ports are designed for racing applications and with unrestricted opportunites for port shapes and designs for maximum flow.


Application of New MDS
Duratec EVO Cylinder Head

The ultimate for high performance

The design has more space for the valve system, matching higher lift camshafts and larger than standard bucket tappets.It comes fully CNC-machined for a superb finished quality. The MDS cylinder head is the ultimate high performance Duratec tuning. It combines uncompromised quality with completely new possibilities for development and performance.



Raised inlet and exhaust ports for high flow efficiency and improved cooling. The standard ports shown in yellow lines
