which throttle body gasket

I have a Professional Products 85mm Throttle body and a BBK intake.


One came with a gasket that that covers up that little whole where the IAC is.

One does not(it has an openning from the throttle body to the intake), this is the one I used.


I'm having idle problems, should I have used the one that blocked this whole?


I have a LS6 with NO emissions.

I can't imagine that blocking the IAC passage would help the idle, so there must be something else going on causing your bad idle. Did you change anything other than the intake?
