Destroking an Engine

I've long wanted to build a de-stroked Ford small block. My thought behind this was fairly simple, Any given port has a max flow rate. Take a medicore flowing head and put it on a smaller displacement and suddenly it's not so mediocre. (BTW this is why I've no interest in a 225, I'm sticking with the 170 slant.) As a bonus you'd gain rod ratio, but that has to be watched as you can go too far. In the case of the SBF the 289 has a 2.87" stroke so I was thinking somewhere in the 2.25"-2.75" stroke range. Use the common as dirt 2V Cleveland heads to build a pseudo "Boss 250" or something. No idea what I'd ever put such an engine in (Locost 7 maybe?), so the idea is still just that.
