Throttle body gasket question.
I'm going to be changing the intake an plenum gaskets on my 89 iroc with a 350 TPI. Since I will have everything apart, I figured I'd change the TB gasket as well. When looking at gaskets, I've always seen that there is 2 TB gaskets included in a set or if bought individually, there is 2 to choose from. From what I've read, 89 was a 1 only year for the TB design. Does anyone know which one I should use in the pics attached? Or do I match the gasket to the design of the gasket surface on the TB? Thanks.

Re: Throttle body gasket question.
Maybe this might help. See post #11:

Most upper manifold gasket sets (plenum to runner) come with both style TB gaskets. Just match up the old gasket to either one of the new ones.
