O/T: Leaded or Unleaded Gas??

Hey all,
I got the '66 MG this weekend for the wife. It's a pretty cool little car. Long story short, right after the guy (he's 75) bought the car(the next day), he had medical problems and wasn't able to drive it. The car was sitting on empty when I bought it and I need to know what type of gas to put in it. The Chilton says it takes Leaded gas, 98 octane! He said when he bought it he put unleaded supreme in it for the trip home, but never thought to ask the previous owner. I know in order to run unleaded gas your supposed to do some head work.

My questions are:
If I run unleaded gas, will it hurt it if the heads haven't been reworked?
If I run Leaded gas will it mess up the engine if it is setup for unleaded gas?(I thought the lead was used as a lubricant)
How can I tell what kind of gas the car needs without removing the head?
Do I really need 98 octane gas?? I know I can add an additive, but really, 98 OCTANE?
Thanks for the help guys!
