This sounds stupid, but I can't find a clear answer.

On the LS6 intake, which ports see both vacuum and boost?

I have the brake booster line T'd off to a vacuum block for FPR/boost gauge reference (the check valve is still on the far side of the line so the booster will only see vacuum), but for the ease of use I'd like to run the BOV vacuum line directly to the intake.

Does the brass fitting in this picture see both?



Thanks!

Yes that brass fitting will see both boost and vacuum

I thought all vacuum ports coming out of the intake saw boost?

The fitting that I believe used to be for the PCV system on the other side of that brass fitting is what I use as a reference. I ran a line from that to a vacuum block and referenced my secondary pump hobbs, meth controller, and BOV from there.
But yeah, that brass fitting sees both as well.

I know, I just wasn't sure if there was a block off in there or not. I figured that out when I actually looked at it in person. I was at home at the time, away from the shop where the car/intake is.
