If you can feel vacuum from the port you used for the vacuum source at idle then you're good. Check to see if the valve opens and closes with it off the car. If it does then all you need to do is adjust spring tension.

Where do the TWO hose go on his blow off valve? If that's a sequential bov, the site I attached in the other post says one should go to a non vacuum source, meaning before the throttle plates. I surely don't know, just read the jpg.
