You have to drill/Tapp the manifold for the BOV. It only needs vacuum.

My reason for utilizing a vacuum block. Tapping the intake manifold or a vacuum block, they both serving the same purpose. Per Sasha advice, it's best for the BOV to have its own vacuum source with the shortest path. Very good advice. Doesn't make it wrong to do. No way between the two is wrong. I got this idea from VipViper who utilized the vacuum block for his build.
