I think I've managed to clarify. I was partly right. The B25 was the earlier EJ257 head the V25B is the latter. They have different cooling passageways and each need a different head gasket design. Ignore what I said about the cam angle sensor I got that bit wrong. I'm still reading up on this so I'll post what I find.
