Default vacum source

Finished build and running well. I have a 4150 hollley on an air gap rpm and the carb bowls cover the manifold vacum which I plugged. If I put a spacer in, there will be a clearance problem I think. I need a vacum source and I am using the carb source for pcv. any suggestions? I only need enough vacum for accessories, no power brakes. Any input is greatly appreciated.

you could always drill and tap another hole in the intake for vacuum. The fittings are available from most of the major parts vendors to than connect your vacuum lines.
