B & J Engineering specialises in the refurbishment of cylinder heads for Natural Gas Engines used in industrial applications. We specialise in the refurbishment of various industrial gas engines and the relative cylinder heads. These include models manufactured by MAN, Ford, Perkins, Dorman, Mercedes and Velmet.
For all of our gas valve seat cutting, we choose to use the Newen Contour EPOC, which provides us with the accurate, gas tight fit that is required. More information regarding Newen machines can be found in the Newen section of our website,
