I've been playing with a similar set-up as has TLowe, I have a problem with it running rough up to the 1200-1300 rpm level before it starts to smooth out, so I'm making some port dividers to fit into the head and intake manifold to try and seperate the flow to each cylinder. TLowe has done it with dividers in the head.
Are you using a Clifford intake also? 292 CI engine?
I am thinking FI would work a little bit better w/an Offy intake, just me thinking out loud.
The way the Clifford has a nice long smooth radius into the # 1 & # 6 ports, most of the air goes to them.
W/a sharp 90 degree turn the Offy has, I am thinking it does not distribute the air/fuel the same way.
Plus I have alway said, the smaller intake volume & runner size the Offy has, it will create better bottom end responce, especially on 250 & smaller engines.
