MAX RPM for modified 305 TPI

So given a modified TPI combination (stock type with aftermarket base, runners and port matched plenum) whats the highest RPM you can achieve while being in range of TPI with a 305? I have seen only seen 350/383 combo's. Shouldnt the 305 be a little higher due to being able to be fed more air given the cylinder size?

I used a calculator that says 461cfm for 5800rpm for a 305 @ 90% VE but I need something more relative, like port size = xcfm for 305ci/8...
