Dual 3" exaust to big for 318?

Hey ya'll, I gots me a little question:
I can get two 3" 40 series flow masters for free. And, since my '77 needs/I want new exaust any ways, I figured what the hell.
Can I run true dual 3" exaust from the headers? My 318 is mildly warmed up, but is getting 340 or 360 heads this summer, and a new cam/timing chain.
So, is it OK?
