I'd recommend Millers VSP additive. It is based on Manganese, which came out much better in tests than the Potassium used in LRP, and also has an octane booster.
I have a Triumph 2000 (as well as a Volvo), and I have used Millers in the original engine since leaded disappeared. It gives excellent pinking resistance and the performance is as good as with the old leaded 4 star.
The valves seem to be holding up - done about 20,000 on it.
Unleaded + Additive works out cheaper than LRP, which in my opinion is rubbish anyway. (It perished new carburettor diaphrams in a matter of weeks)
It is the best 'do nothing' option until such time as you need a head overhaul anyway.
