Talk with Tony at Mamo Motorsports. He does a lot of work with the TF's and he can definitely get ya what ya need. I was looking at them for my CTS-V. Definitely a good buy!

I ended up pulling the trigger on these. Getting them through TEA. Had them mill for a 64cc chamber and they will be putting there final touches on them as well. Can't wait to see what they do.

Bad ass!! The 370 im building is getting them too. Just out of the box though. I can't wait!!

Yea I'm pretty stoked they should be a work of art can't wait!

All Tea does is there priority valve job and that bumps flow about 6cfm as advertised as I remember, Mamo re shapes the chamber a little bit, so I'm told, to what I dunno. I'm sure it's worth it.

As for my experience my setup with 10*smaller intake/ex and cam made the same as my l92 headed 408 sorry it wasn't a very good comparison. Makes good torque early on but that could just be my combo.

I was gonna pull the trigger on a set of these but decided on the tfs 245 with the nitrous exhaust port
