Base level 350 is the 260HP version, same engine as mine (it's on engine stand now...waiting on a few parts before install). You might be able to get away with bigger cam because of your auto tranny. But be careful. Boot85 is right, smaller valves and lower duration cam, smaller tube headers (and smaller 4 barrel carb) give you better low end grunt.

I would seriously consider starting with Performer intake and keeping everything else as you have it (stock heads, cam, Edelbrock 650 carb). You would really hate yourself if you spent all that $$ on heads, cam, etc., and didn't have the low end you want.
