- Mash specifications changed across Euro standards. Compare the original cylinder head, piston type, emissions port, cam/tachometer arrangement and rocker-cover pattern before fitting.
- Later water-cooled / Euro 5 Mash engines are not included.

Before Ordering
Confirm the full engine code and compare the cylinder-head casting with the original. Check the cylinder-head stud layout, camshaft and timing arrangement, inlet and exhaust ports, secondary-air / EGR provision, tachometer-drive arrangement where fitted, rocker-cover mounting and piston type.
Do not order solely from model name or engine capacity. Similar 157FMI-family engines can use different head castings and emissions systems.
Installation
Cylinder-head replacement requires correct cam timing, valve clearances, clean gasket surfaces, unrestricted oilways and the correct torque procedure. Professional installation is recommended.
