Which heads are best

I just got my 408 short block back from the machine shop and was wanting some opinions on which heads to use and where to get them. Its a 1972 260 block bored .030 with a 4 inch forged crank, eagle rods and forged probe flat top pistons with the 2 valve reliefs. They are zero decked. I am putting it in a 1970 340 Dart Swinger body that has power steering, power brakes, and air conditioning, all of which I intend to use. 3.23 Posi rear and 727 automatic. Not a race car, just a cruiser. I dont want to get too radical with the cam but I do want a little bump at an idle but I want all the power brakes and air to work good. What cam combos will work good and what kind of aftermarket heads will do the trick out of the box. I plan on buying the heads and assembling this thing in the next couple of weeks so no waiting for machine shops to get around to doing anything.
