Default Oil pump or intake Manifold Vacuum hole bolt

I replaced that cheap screw in bolt they sell, because when I went to unscrew it, the top stripped. I replaced it with an easy to remove brass bolt. Its the bolt below in the picture.

That's a 1/8 pipe thread, not a normal thread.

That's the bolt I installed, a 1/8 pipe thread bolt.
