Used BMW M5 Cylinder Head

No — these are completely different generations with completely different engines: the E39 M5 (1998–2003) uses the S62 V8, while the E60 M5 (2005–2010) uses the S85 V10, so the cylinder heads are not interchangeable at all. Always confirm the exact engine code from your V5 or a VIN check and supply it to the breaker when requesting a quote.

The E60 M5 ran from 2005 to 2010 and all used the S85 V10 engine throughout that generation, so a head from a 2006 car is likely to be compatible with a 2009 car in principle. However, ancillary fittings and any mid-production running changes could affect the swap, so confirm the exact engine code from both cars with the breaker before buying.

The Competition package on the F10 M5 (2011–2016) is a chassis and suspension upgrade, not an engine change — both use the S63 twin-turbocharged V8, so the cylinder head is the same part and trim level makes no difference to fitment here. You may find cosmetic differences on ancillary parts or covers, but the head itself is not affected by whether the donor car was a Competition model or not.

No — the F90 M5 (2017 onwards) and the F10 M5 (2011–2016) both use an S63-derived V8, but the engine was significantly revised for the F90 generation and the cylinder heads are not a straight swap between generations. Confirm your exact engine code with the breaker, as they will need to verify part numbers across those two generations before supplying a head.

Yes, the engine code is the single most important detail for sourcing a cylinder head — it takes priority over the year or model badge. Always give the breaker the engine code exactly as shown on your V5 or VIN check, rather than relying on the year alone.

The cylinder head itself is the same regardless of gearbox type on the E60 M5, as it is determined by the engine code (S85) and not the transmission. That said, confirm this with the breaker against your registration to rule out any ancillary differences on the specific unit they have in stock.
