The 292 rockers are actually just a tad bit larger at 1.74 or 1.75, I forget which.
The 235 and 261, yes, I agree 1.4 is probably right as I seem to recall they are commonly described as being just under 1.5. There were a couple of companies back in the day that sold off set rockers for either the exhaust or intake, I forget now, B&B was one company, there were others. Over the years I have kept my eyes out for a set mainly just to have as I dont think I would actually use them.
