Generally the additives provide an alternative lubricant to lead - typically
phosphorus, sodium, manganese or potassium. Only if specified will they
raise the octane level as well, otherwise it remains the same as the base
fuel.

You basically have two choices:
1. You have a head conversion which means the valve seats get replaced.
This usually costs around £200. There are plenty of places that now provide
new heads which have the seats already replaced.
2. You can use an additive which I believe increases the octance level to
avoid pinking.
