At the moment i've got an '87 mayfair leaded engine. Im wanting to change this to unleaded. All I need is an unleaded head right?

Yeah but you might aswell invest in a better (ported/flowed) unleaded head while youre at it for the sake of another 100 pounds you'll get better peformance.

You may need to re-tune it slightly for the new fuel, and you might find that some of the parts in your carb or fuel pump don't like unleaded but it should be ok.
