I've just bought a 1968 500f which has a 126 engine fitted to it. It hasn't been converted to run on unleaded, so I was thinking about having hardened valve seats fitted to the cylinder head. I've read an article in one of the classic car mags which says it's not a good idea to do this as the head is made of alloy and the seats can detach over time. Has anyone had any experience of this? Conversely, has anyone had the conversion done and never had a problem with it?
