Spark plug gap for a 302

My 66 has a 302 in it, however, I am unsure of the year. I am replacing the spark plugs and would like to know if there is a general gap setting for it. I would appreciate any help I could get on this matter. Thanks.

For a point type ignition, use 0.035. For electronic go with 0.042. That's a good starting point. If you have high compression or forced induction, go a little less.
