Special LPG Cylinder Heads

Cylinder heads subjected to LPG operation tend to suffer from valve sinking into the valve seat due to the increased combustion temperature and lack of lubricating qualities of LPG. 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 reasonable value and seat durability, however when the valves eventually fail, we can improve on the original valve and seat combination to further improve valve life.

Abba Engine Reconditions have been modifying cylinder heads to suit LPG operation for over 15 years and can guarantee our LPG cylinder heads will last for the long run. Our cylinder heads which suit LPG operation typically have a full set of K-Line bronze valve guides, Serdi LPG valve seat inserts, and tufftrided sometimes stellite faced valves.
