An internal combustion engine system includes a cylinder block, a plurality of bite rings, a cylinder head, and a head gasket. The cylinder block defines a combustion cylinder. The plurality of bite rings encompass the cylinder. The cylinder head is coupled to the cylinder block and covers the combustion cylinder. The head gasket is disposed between the cylinder head and the cylinder block and is structured to engage with the plurality of bite rings. The cylinder head may further include an expansion groove that is disposed between adjacent ones of the plurality of bite rings and extends in a circumferential direction around the cylinder head.

A valve spring retainer for an internal combustion engine includes a body having a lower portion and an upper portion. The lower portion defines a radial flange and a first opening extending axially therethrough. The upper portion includes a first wall and a re-entrant lip. The first wall extends at least partially axially away from an outer perimeter edge of the radial flange. Together, the first wall and the radial flange define an open reservoir for receiving and retaining oil therein. The re-entrant lip extends from an outer end of the first wall at least partially radially inward toward a central axis of the first opening. The re-entrant lip extends over a portion of the reservoir defined by the first wall and the radial flange.

Systems, devices, and methods are disclosed for clamping an exhaust manifold to a cylinder head with at least one clamp that is configured to allow thermal expansion and movement of the exhaust manifold while preventing exhaust leaks through the exhaust manifold and cylinder head connection.

Systems, devices, and methods are disclosed for supporting one or more camshafts by the engine block in overhead arrangement relative to the cylinder heads and valve train.
