Thats what i said
, you also want to tie the primarys to each other and the secondarys depend on what the aplication is but having a plenum on the primarys and not on the secondarys can make some odd things happen depending on the carb or ECU.

While there will be some vacuum from the secondary ports, the secondary throttle plate on the Sterling should do a good job of closing it off.
just have a nipple on each plenum and use a T connector to tie them to the MAP or if carb just cut a ľ inch square to connect the two plenums right at the carb.

I am against this 100% over lap for VE is WAY
over rated, I vote radius the edge and done for NA, and never run with out sleeves. I also run tear drop shaped bridge's, Keep that over lap to a minimum.
