3. Is my engine interference cylinder head, or non-interference?! Just checking in case we get things wrong - different sites say different things, Haynes says the B230 is interference.

Chris,
My understanding is that the carburettor engines have flat topped pistons (lower compression), and are all safe. The fuel injection engines have domed pistons and are interference. This is only what I've read, I've never had a fuel injected Volvo; someone much more knowledgeable than I (like Loki or LS) will know the answer.
To be candid, this is a pretty simple engine: SOHC and just 8 valves, there is no reason to get this wrong. Take your time, check everything and it should be fine.
Alan
