Your engine has a compression ratio of 7:1 and gas of 70 octane is recommended. So, regular 87 octane will be fine.

In 1948 low lead and no lead gas was common. Large amounts of lead additives began to be used about 1955. It is the 1955 - 1970 models that need lead.

You can add some upper cylinder lube to the gas to protect valves, rings and cylinders. Redex, Bardahl, Marvel Mystery Oil or some prefer 2 stroke oil. Some believe this extends engine life between overhauls, others don't bother. It's up to you.
