The hole goes into the manifold. I wouldn’t let the drill but go any deeper than necessary to breakthrough the wall of the manifold. I measured 4-1/4” before the drill would come into contact with the #7 runner.

I put light in #8 runner so you can see it lighting up the booster hole.

I’m sure the drill bit will try to pull through when it breaks into the inner wall. That’s why you should use the shortest bit possible.

I let GPI do the mods on mine.
