1965 283 Spark Plugs and gap?

Hey guys - I'm going to change the plugs in my 283. I believe it's a 1965...engine number is 829482. The plugs currently in there are autolite 303's. What are you guys using for plugs and is there a recommended gap for these motors? TIA

The original manual says UJ-6 at .028 gap. J-6 is probably the current replacement
