Chevrolet / Daewoo B10S1 Cylinder Head Assembly – Matiz / Spark / Aveo / Kalos
This Chevrolet / Daewoo B10S1 cylinder head assembly is a brand new, factory-fresh replacement for the 1.0-litre inline-4 petrol engine used across the Matiz, Spark, Aveo and Kalos ranges. It is supplied with valves and camshaft fitted — intake and exhaust valves, springs, retainers, stem seals, guides and the SOHC camshaft with rocker assembly are already installed, so the head arrives ready for installation after transferring your external components.
The B10S1 is the 1.0-litre four-cylinder member of the Daewoo S-TEC engine family, produced from approximately 2002 to 2009 and fitted to the smallest models in the Chevrolet and Daewoo ranges. It is a SOHC 8-valve design with an aluminium cylinder head, a belt-driven camshaft and mechanical valve lifters — there are no hydraulic tappets on this engine, so valve clearances must be set manually during installation. These engines remain in daily service across Eastern Europe, Russia, South America, the Middle East and Asia, and the cylinder head is a documented replacement item on high-mileage or timing-belt failure examples.
What’s Included – Fitted to the Head
- Complete cylinder head casting — precision-machined and pressure-tested
- 8 valves — intake and exhaust, heat-resistant (2 per cylinder)
- Valve springs, spring seats and retainers
- Valve stem seals and valve guides — fitted
- Camshaft — SOHC, 8-valve profile
- Rocker arms and rocker shaft — fitted
- Camshaft bearing caps — torqued to specification
- Core plugs and oil gallery plugs — installed
What you transfer from your original head: valve cover, timing belt kit (belt, tensioner and idler), head bolts (always fit new stretch bolts), head gasket and remaining gaskets, fuel injectors, spark plugs, ignition leads or coil pack, intake manifold, exhaust manifold and any sensors or brackets mounted to the head.
