This topic has been discussed but I think this article from MiniMania by Keith Calver is worth reading. His conclusion is that an additive is the best choice.

Oh dear KC.....
Depends on the use of the car - IF going to drive it hard and long - then best option without a doubt is a proper unleaded head conversion. If just normal running/limited Mway(Freeway..) running then don't bother wasting money on additives - but DO set the exhaust valve gaps at 15 thou, and check/reset them every 3000 miles. It will be fine.
