1984 Esprit Turbo - unleaded fuel?

[tprwi2]

Is my 1984 Esprit Turbo 910 Engine suitable for running on unleaded fuel without additives? I've got the engine out at the moment and the head looks in good condition. If not suitable for unleaded then I may as well go to the expense of getting new valve seats and guides, otherwise I'd rather not do it as it's costing enough getting the rest of the engine back together. Any advice welcomed - Thanks

Yes it's suitable. As a preference I tend to use Super unleaded (Tesco sell 99 RON) or Shell Optimax in mine.
