best 2bbl carb for /6 225 super six manifold.

Point taken. going to see how this carter works at first. It is OEM. I am wondering now if they have a good rebuild kit, probably will need one.
I would try to find the most modern rebuild kit I could. That way you'll get the latest ethanol friendly gaskets and parts. I suggest contacting Daytona Carburetor. They are very good.
