Ok TB's are in.

So front lips gone to 2.64" and tapers down into the center but now there's no more lip. The middle went to 2.51" as far as my calipers can get in from the front. 2.49" now on the back lip which now looks port matched to the manifold!!!! I might have a little sanding to do on the mani, won't know till I bolt them up. And as far as I can get in on the back side closest to the butterfly, it's now 2.48"!

So before 2.6 to 2.5 but then 2.5 down to 2.35 at the butterfly, then back up to only 2.39 at the mani.

Now 2.64 to 2.51 but only down to 2.48 at the butterfly, then to 2.49 at the mani.

I wish the new butterfly was knife edged though.
