brake booster hose ??????

so on my 89 m20b25 that i just swapped into my 87 e it has two vacuum hose ports on the throttle body that mate with that check valve thing then goes down to the brake booster. i have seen some e30's with only 1 hose would it be okay to make it have only one hose if i have that other check valve? couse i don't have the intake boot that has the vacuum line that goes to one of those hoses.

Yeah it'll work fine. You just have to plug the 2nd port on the rear side of the throttle body.
