tunnel ram/ carburetor booster question

i recently purchased a weiand tunnel ram for my 505" wedge, i purchased two used holley 4779 750 double pumpers that i plan to rebuild and convert to e85 using the quickfuel metering blocks. i didnt realize until i got the two next to eachother that one has the "downleg" boosters and the other does not.

my main question is is this a big enough issue that i should pursue another carb with matching boosters or would it be a small enough difference to not make too big of an issue. im sure theyll be slightly off just not sure if its an extreme amount that will lead to tuning issues down the road...

any help is greatly appreciated thank you!
