GAZ / ZMZ 406 16V Cylinder Head Assembly — 5-Bearing – GAZelle / Volga / UAZ

This GAZ / ZMZ 406 16V cylinder head assembly is a brand new, factory-fresh replacement for the 2.3-litre DOHC petrol engine used across the GAZelle, Volga and UAZ ranges. It is the 5-bearing version of the ZMZ-406 head — the later, stronger design with five camshaft bearing caps — and is supplied with valves and camshaft fitted according to your confirmed stock configuration.

The ZMZ-406 is a 16-valve DOHC engine developed by the Zavolzhsky Motor Plant (ZMZ) and fitted to a huge range of GAZ and UAZ vehicles from the late 1990s onward. It is the 16-valve successor to the 8-valve UMZ-4216 and produces significantly more power and torque. These engines are still in daily commercial service across Russia, the CIS and export markets, and the cylinder head is a documented replacement item on high-mileage or overheated examples.

What’s Included — Fitted to the Head (Confirmed Configuration Only)

• Complete 5-bearing cylinder head casting — precision-machined and pressure-tested
• 16 valves — intake and exhaust, heat-resistant (4 per cylinder) — if your stock is a valves-installed or fully assembled version
• Valve springs, spring seats and retainers — if valves are fitted
• Valve stem seals and valve guides — fitted
• DOHC camshafts — intake and exhaust — only if your stock is the fully assembled RHD-002ASSY configuration (406.3906562 / 406.3906562-10); the standard 406.1003009-5 and 406.1003009-30 are bare or valves-only heads
• Five camshaft bearing caps — torqued to specification — if camshafts are fitted
• Core plugs and oil gallery plugs — installed

What you transfer from your original head: camshafts and bearing caps (if not included in your stock), hydraulic lifters, valve cover, timing chain kit, head bolts (always fit new stretch bolts), head gasket and remaining gaskets, fuel injectors, spark plugs, ignition coils or leads, intake manifold, exhaust manifold and any sensors or brackets mounted to the head.

Vehicle Compatibility — Engine Code Detail

The Short Description lists the basic model range. The fitment below is the engine-code level detail needed to confirm the correct casting before ordering. The 406.1003009 casting is shared across ZMZ-406, ZMZ-405 and ZMZ-409 applications, but camshaft profiles and emission equipment differ — match the OE suffix and bearing count to your original head.

• GAZelle (3302, 2705, 3221) — ZMZ-4061.10, 4063.10, 40637.10 (Euro-2 and Euro-3 builds)
• Volga (3102, 31105) — ZMZ-406.10 and related 406 variants
• UAZ (Patriot, Hunter, 3162, 3303) — ZMZ-406 and 406.1003009 variants as fitted from the late 1990s

This cylinder head is the 5-bearing ZMZ-406 16-valve casting. It is NOT interchangeable with the 3-bearing ZMZ-406 head, the 8-valve UMZ-4216 head, or the 2.7L ZMZ-409 head.
