Abstract: A cylinder head for an internal combustion engine includes a cylinder head body forming an injector bore, a fuel gallery having segments extending collinearly, two fuel supply passages in fluid communication with the fuel gallery, and two cross-drill passages terminating at a respective cross-drill opening. The two cross-drill passages extend generally parallel to the segments of the fuel gallery and are disposed at an offset distance therefrom such that the cross-drill openings are disposed closer to the right or left side of the cylinder head body.
