Well its really your choice.

Being a very high mileage 240 estate I've had exhaust valve burnt because of the greater heat generation. But this was at 350k miles.
I put a rebuilt head on, they said do want inserts, and as I thought that all Volo heads were hard, I said no. That head lasted 20K.


I would say a 940, as late model RWD Volvo it will have hard inserts so unless you propose to do 300k+ you should be OK. There is information on this site which will inform you when hard engines were introduced, all to do with leaded/ unleaded petrol.

Remember LPG lub. is not cheep and it needs to be adjusted between 0-flood, though this is easy.
