In general: smaller volume = higher compression = more pull but better fuel needed; larger volume = lower compression, the engine revs out more freely and tolerates pump fuel. If in doubt, take the standard.
Based on the VHM manufacturer charts.

Exchangeable combustion chamber (insert) for the VHM cylinder head AA33112. Chamber volume 5.40 cc. 🔴 The insert fits ONLY the VHM head AA33112 — it cannot be fitted into the OEM head. For the stock (OEM) piston. Compared with the VHM standard (5.20 cc) it has a larger volume, i.e. lower compression: better over-rev and more top speed at the cost of bottom-end response. It also tolerates lower-octane fuel. Quick to change — the insert simply sits in the head and seals with O-rings. The last characters of the part number are engraved on the insert, so you cannot mix them up. Fits: KTM 65 SX (2009–2023); Husqvarna TC 65 (2017–2023); KTM 65 XC (2009–0); KTM 65 SXS (2012–2015); GasGas MC 65 (2021–2023).
