Abstract: A cylinder head [20, 120] mountable onto a cylinder block [16] of an engine [10] is disclosed. The cylinder head [20, 120] includes at least one fastener boss [28, 128] configured for receiving a fastener [24], and the cylinder head [20, 120] is securely fastened onto the cylinder block [16] of the engine [10] by the fastener [24]. A boss cutout [30, 130] is formed on a lower portion of the at least one fastener boss [28, 128] that abuts the cylinder block [16] such that a contact pressure balance of sealing pressures around the cylinder block [16] is evenly distributed.
