The TPI from the factory was designed for emissions compatability. If memory serves me the 350 tpi's had larger runners than the 305's did. I would find a 350 TPI off of a Vette (verify verify verify) if you can and I think you will get the flow you're looking for.
I have thought several times about using the whole topend off of a early 90's Vette with the roller cam and aluminum 58cc cylinder heads on a 283, I think it would be a screamer, over active brain sometimes I think...
