Brake booster hose attaches to the rear of the intake manifold.
On the left of the intake near the throttle body you will need a 3/8” vacuum cap to plug and unused EVAP port. It’s used for emission purposes, not ours. It can be used as a vacuum source if you need one.

The crankcase fresh air inlet on the left side of the intake will need a filter. I used a K&N crankcase breather pn# KNN-62-2480
