Here we have a new Alvis Speed 25 Aluminium cylinder head, complete with valves and springs. This is one of the last made by the excellent Dick Leeksma. The casting is of a very high grade, the finish and machining is to a much higher standard than other castings we have seen. An ideal spare to have just in case, especially if you race or rally...
