I got my old motor in the truck and running yesterday and now its time to work out the details. Motors a .040 327,11:1 forged pistons, Solid cam .558 lift, Heads are Dart 215's cnc ported and matched to a single plane bowtie intake, with GMPP rockers and pushrods and a 750hp Holley. My questions are with a single big port on the carb for vacuuum how does everyone plumb their PVC and power brakes? This combo has very little vacuum, havent had a gauge on it yet. Dont really want to drill and tap intake. Do I ....

1. Spacer with vacuum port for brakes and Pcv to carb.
2. Pcv to aircleaner base and brakes to carb.
3. Either option with a vacuum reserve canister in line before booster.

Im sure Im not the only one with this problem. Just looking for the easiest soution.
