It is supplied fully assembled as an aluminium unit with valves installed where applicable, machined to original equipment tolerances and pressure tested, making it a dependable replacement for a warped, cracked or valve-damaged original head.\u003c\/p\u003e\u003cp\u003eKey Features: The casting is produced from high-grade aluminium alloy and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are installed and honed to deliver even sealing and balanced compression across all four cylinders. Machined cam carrier surfaces maintain correct bearing clearance in the DOHC 16-valve layout, and the intake and exhaust flange faces are finished for reliable gasket sealing. The lightweight aluminium construction also assists heat dissipation in this small-displacement engine.\u003c\/p\u003e\u003cp\u003eVehicle Compatibility: This head fits Chevrolet Spark M300 (2010-2015), Spark Classic (2016-2020), Spark GMSA (2011-2017) and Spark Europe (2010-2020) models, plus related Aveo, Matiz, Daewoo Kalos and Ravon applications using the B12D1 or B12D engine.
