You are correct, the 2100 does have 1-1/16" venturi's, but it has the same air-horn and valve body as the EBU. The '56 Holley 2110 had a larger air horn, including the provisions for the automatic choke and larger bores in the valve body.
All three carbs (EBU, 2100 and 2110) have exact same mounting bolt-hole pattern, but the EBU and 2100 can use either '54 or '55 oil-bath air cleaner, while the '56 air cleaner will not fit on the '54 & '55 and vice-versa.
Yes the EBU was used on the '54 239 Y-block, but many '55 272's also had the EBU (possibly only early in the model year). My '55 came with an EBU when I bought in in 1972 and the car still had the original Power-Punch battery. It was pretty obvious the previous owner had never done anything to the car but change tires.
Back in the early '70's, I used to go to a junkyard about 25 miles from here that had three rows of '55 & '56 Fords. More than half the ones I looked at had Ford EBU carbs. All of the ones they had were 272's. There were no 223 I-block 6-cyls in the bunch. Back in the '90's, I went back there again and they were all gone.
