• an engine block comprising a cylinder;
• a cylinder head mounted to the engine block, the cylinder head comprising an intake valve seat and a shroud and a block mounting face, the shroud comprising an edge;
• a combustion chamber formed at least partially by the cylinder and the cylinder head, the intake valve seat configured to allow an intake flow into the combustion chamber;
• and
• an intake valve, the intake valve configured to travel between a fully closed position seated against the intake valve seat and an opened position displaced from the intake valve seat allowing the intake flow through the intake valve seat and into the combustion chamber;
• wherein the shroud only partially surrounds the intake valve and extends along at least a portion of the travel of the intake valve so as to restrict the intake flow along only a portion of the intake valve, and the edge intersects the block mounting face.
