Cylinder Heads are produced mainly in cast iron, though the company is developing aluminium heads for specific applications. These casting are made at one of the Shriram Group's own foundries which is the largest, and technically the most advanced, in the country. The cylinder heads are manufactured using shell moulding casting process to achieve a uniform wall thickness of the water jacket.

The casting and the water passages are cleaned using the shot blasting process, and the heads are machined using highly sophisticated CNC machines that yield excellent dimensional accuracy. Advanced testing using processes like Metallurgical Testing, Hydro-pressure Testing and Vacuum Testing is carried out to ensure delivery of a defect free product to the customer.
