Same issue with putting LD4B intake on. Carb plenum gets in the way and no room for torque wrench on middle bolts. MAC tools/Toolmanmike sells an adapter wrench that fits torque wrench.
PITA without one.
First get them nice and tight with a combination wrench...
Then torque the outer ones in sequence...
then put the combination wrench on a torqued bolt to get the feel for how hard it should turn...
'
Then go back and tighten the center bolts to that same feel....
