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 AA33145. Chamber volume 8.00 cc. 🔴 The insert fits ONLY the VHM head AA33145 — it cannot be fitted into the OEM head. This insert is shaped for the VHM piston with a 12° dome (APKT08521707). Do not use it with the OEM piston — the lettered inserts are for that. This is the VHM standard insert for this head — the default choice if you are not sure which one to pick. 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: Husqvarna TC 85 (2014–2017); KTM 85 SX (2013–2017); KTM 85 SXS (2013–2015).
