Cylinder heads subjected to Cylinder operation tend to suffer from valve sinking into the valve seat due to the increased combustion temperature and lack of lubricating qualities of Cylinder . Cast iron cylinder heads without valve seat inserts are especially prone to valve seat recession. Some cylinder heads, especially those from unleaded vehicles, often have a reasonable valve and seat durability, however, when the valves eventually fail, we can improve on the original valve and seat combination to further improve valve life.

We at Sunbury Cylinder heads help in maintaining your Cylinder head in the right condition to improve its lifetime.
