How are Cylinder Heads Remanufactured?

When HHP receives a core cylinder head to be remanufactured, the first step is to remove and throw away all the valves, springs, retainers, keepers, valve seats, and injector tubes. The cylinder head is then cleaned and prepared for the repair process. It is heated in a controlled environment to a temperature of more than 1000° F. 

At this point, any cracks or imperfections are repaired by a process of re-forging. This process is done by a trained welder introducing molten cast iron to the area to be repaired at the same time the parent metal is flowing together to make a homogeneous bond.

The cylinder head is then cooled at a controlled rate. This has been proven to eliminate crack formation. Next, it is machined and set to manufacturers specifications using all NEW parts on assembly.
