360 heads on a 318 of any benefit?

My 318 is close to running right. There's the small issue of vac advance and the cold start issue.

This 318 is equipped with hooker performance headers and will be getting a dual plane edelbrock with 4bbl 600 cfm edelbrock carb in about a months time.

While the intake is off I'll be putting in either a stock 340 cam or an MP equivelant, maybe 1 step choppier, it still needs to run right for the street.

Will the engine benefit with 360 heads? I just came across a set cheap.

Either way I'm going to bust out the dremmel and flow the heads in any case.
