NGK TR 55's (note the 55) are the most common. Gap them at .050-.055 and you're golden.

NGK TR 55's (V power) not (G power) Cost about $2.00 at any auto part store
Gap them at .059 factor gap .060
They work great, smoother idle.

Sorry I thought I put 55's.

As for a camed car you can still run the TR55's if you are spraying run a TR6 or colder plug.
