I have just swapped out an unleaded 998auto for a 1275 VP auto. You can have the 998cc unleaded cyl head for £30, I would advise that it's skimmed though as the head gasket had gone.

Is there any way to tell from the colour of the heat outside if it has been converted

You are going to get the valve seats replaced or buy a head which is known to be an unleaded head (seats replaced) and thats either new or second hand.

You can not tell by sight if they are unleaded seats.

Have you tryed Castrol's octane booster and valve seat protection product? You might want to give that a go, I know people who have used it with no problem with super plus for MGB's. Having the valve seats replaced can if you have it done properly by people who actually know what they are doing be rather expensive. This product only costs about 12 quid.

Sticking oily type stuff into the tank is for days of old! It's like two stroke pre mix - dont forget to shake the tank! Getting the valve seats done is the way to go. Why should you have to pay the premium of super unleaded and however much the bottled gear is just to run an old car? Getting the valves done would pay for itself the more miles you do - so do it and get out there!

I agree.

Or even better, don't change a thing and only get a new head or fit new valve seats IF you start having worn valve seats.

If the engine is old enough to not not have hardened valve seats, it's probably old enough to die of old age before you even have to worry about worn valve seats.

I think that may well be a better option. Certainly with Rover SD1's people worried an enourmous amount about wear, only to remember that the car was designed to be exported to the U.S, thus it was designed to run on unleaded anyway. This may well be the case with your engine.
