The annular boosters took rat bastid a little bit of work on a lathe because blp haven't made banjos specifically for their main body .
Holley's main bodies use a square notch, blp has a round locator hole for the banjo, so it just needs to be milled a bit to get the banjo far enough in to be swedged in.
Blp will install them for you for an extra charge.
I think all carb builders would recommend annulars by now, they are far superior to a down leg, I can't even imagine how efficient they'd be on a tunnel ram,
I'm thinking you'd have a nice fuel fog.
But on a 750 main body I think it may hurt flow a bit but have a very good signal on those boosters
