400hp 360

I want to go with iron heads. I heard that you can put the big valves in the 302 heads and get the compression ratio up. Would I be better off doing that or run some other heads. If I should run other heads what ones should I run. Is the RPM air gap a better intake on this application and the mopar m1 single plane. I will probably run a thermo quad. Im not on that tight of a budget, I just want to do it right.
