What is a good 4bbl carb for a 318 engine?

I second the 360 heads on the 318 but I don't know about putting 2.02 valves in if your not going to build up the rest of the engine. I would just leave the 1.88? valves in it, get an intake, carb 600cfm, a MP 260/268 cam would really wake that up for not to much money and a set of headers.
