Identifying Carb rubbers

[SteveNC35]

So I've taken off my carbs and I took the rubbers off of the heads as well to clean underneath them as there was a ton of muck there causing them not to seal properly. In my haste, I completely forgot to take note of which way they go back onto the heads and which rubber (A or B) goes on which intake! Is there any way of finding out?

Don't nc35 ones have the cylinder number stamped in, either 1-3 or 2-4?
