correct

Boost Gauge- anywhere on the IC piping
Wrong again, engine vacuum

"boosting the crankcase" is dealt with through valve cover breathers/ pcv breathers.
Wrong again, on L36/L67 motors, there is a fresh air draw in the throttle body that has to be blocked, on L26 intakes, the fresh air draw is on the top of the intake, and can be capped or left open.
