I don't reckon you'd need to go that far. Just get an exchange reco head with gas valves (hardened) and it should last for years.
Mine had a reco head put on around 2008 (before I had it) and it was run on dual fuel till I got it (only petrol now). As far as I know, there was no other work done apart from the head and it just clicked over 430,000kms.
But yeah:
